Here it is guys. As you can see these are long tubes and are made to bolt directly to your factory or aftermarket mufflers. I've only road tested thus far and the car sound pretty good even with the stock mufflers. It's quiet at idle but sounds good when your motoring through the gears. It may be a bit tame for some but I believe everyone should hold off on mufflers till they hear the system with stock mufflers. I believe for some this may be the perfect set-up.
We will dyno test and tune tomorrow as well as check the efficientcy of the stock mufflers. Hang in there as we bring more info your way. Thanks.

Looks real sharp fellas.

Welcome to the G8 Boards.

Thanks
Mike Haddad

Don't forget to send me a system when you are done ! My G8GT is begging for these !

These look totally sweet! I still think that going with Magnaflow mufflers would be better than leaving the stock ones on.

American Racing Headers & Magnaflow mufflers sound like a possible combo. :yumyum:


...

those look niiiiiiiice cant wait to see the price and some dyno #'s !!

i9 agree man hope they are affordable

Great looking product! It looks like they are only compatible with the stock mufflers or aftermarket "Axleback" muffler assemblies. Wouldn't the Magnaflow and Borla Catbacks would require modification to bolt up since they are designed to bolt to the stock cat-pipes?

Would it be possible to change the ARH catpipes to mate with the OEM style connections on the available aftermarket catbacks or will ARH be offering the companion Axleback assemblies?

Awesome looking product, your great reputation is well deserved!

Guys, Dyno testing is being done as we speak. To say this is an eye opener is a major understatement. We tested the stock mufflers with our system by completely removing them. The difference was gains of 2 rwhp and 3 rwtq. With our system the factory mufflers flat out work. Later today I'll have all the dyno results. You guys are in for a treat.

Very interesting result. Having personally cut open the stock mufflers to see how convoluted the flow path is I am very suprised there was not a substantial difference in power production. Heck the muffler's inside tubing is 1-7/8" I.D.!!......

Can't wait to hear sound clips with this system in conjunction with aftermarket mufflers.

S.F.

Seem like you guys need to be sponsored!!! Hit me a PM! :D

You need to keep in mind that this car has no other mods. As power increases through heads and cam or perhaps a supercharger, I can see how upgrading the mufflers could be beneficial. Some will just want the more aggressive sound at idle which the stock mufflers won't give you.

Nick

Or weight reduction... :judge: I dont know how much the mufflers weigh on the G8 but they are pretty heavy on the GTOs.

That's a valid point JuniorSS

As the exhaust gases cool the gas compresses which requires less ID. It is at the Header/Cat/X-pipe area that you need to best size & flow to maximize exhaust gas velocity. People always forget that as the exhaust gases cool you need less ID pipe the further back you get to acheive the necessary flow. By the time you get to the muffler, most cars won't see hardly any benefit to a 2.5" or 3" pipe versus even a 1.5" pipe. Therefore, I have no doubt this system would work well with stock mufflers for most of the "BPU" cars out there.

It looks like I might be sorry that I jumped on the Magnaflow Cat-Back bandwagon so quickly.

Warning, barrage of questions incoming...

Are those cats I'm seeing?
Is this system "legal"?
Any dyno numbers yet?
Is it much louder than stock? (Personally I hope not, sleepers rule:gr_devil:)
Any rough estimates on cost?
Any tests done with a CAI?
How hard are they to install?

That's all I have for now. :)

good questions. . . im interested as well

I am very interested in this header system with the stock rear exhaust. Nick, I am interested in the power #s and price. Looks like a very high quality system.

nice looking product.....very interested as well.

Those are 200 cell metallic substrate cats you're seeing. The cats do have an EO number but the system as a whole is for off road use only..:wink2:. On this application the CAI was worth 5 rwhp and 7 rwtq. The install is very simple. It will take you longer to remove the stock set-up than install ours. Figure on spending 2-1/2 to 3-1/2 hours total if using a lift. Those that do this for living will probably have the job done in 2 hours flat.

There will be a new post showing all our dyno results performed by Brian at Kaltech but I'll give some preliminary stuff.

Stock on Kaltech's Mustang chassis dyno- 288 RWHP 300 RWTQ

AR Headers system only (w/stock mufflers)- 326 341

Same as above but w/stock mufflers off- 328 344

Add Roto Fab CAI- 333 352

Add Tune 343 RWHP 360 RWTQ

Total is 55 RWHP
60 RWTQ

I believe you'll agree these are quite impressive results. I'll have Brian get the dyno graph up. I recommend anyone interested to pm me for pricing. Thanks for being patient.

Nick

40 HP and TQ just from headers?!?!?! yes please... i wonder with full 2.5'' or 3'' exhaust, if those numbers would go up even more...

So, headers, CAI, new mufflers, and we're talking 400hp at the crank? There's the LS3 bloodlines. So, essentially, if the G8 were equipped like a vette, it would make this type of power?

Was this utilizing 93 octane fuel?

40 HP and TQ just from headers?!?!?! yes please... i wonder with full 2.5'' or 3'' exhaust, if those numbers would go up even more...

I doubt if you'd see anymore considering we only picked up 2 hp with the mufflers off the car.

Everything was done with 91 octane as that's all the owner has available in his home state. The car is setup for 87 octane from the factory so simply adding higher octane won't gain hp, it'll just drain your wallet faster.

All gains from the exhaust and CAI were done with a completely stock tune. The file wasn't even pulled from the car until we were ready to start changing it so all of these gains from the exhaust and CAI were true "bolt on" gains.

Holly SHEET! Those are great gains. It looks like those manifolds really choke the power of these engines.

Will you be testing 3-inch catbacks in the future before heads/cam/supercharging, for referrence?

I'm not too suprised that the mufflers didn't restrict power at this level too much. Isn't it said that the further away the restriction is from the engine the less influence on power it will have? I'm by not means an expert on anything, but I try to learn all I can.

Great numbers!

Whoa whoa whoa... the 333rwhp was ALL done with the stock tune? 45rwhp with bolt-ins... impressive. I'd almost expect MORE power out of the tune then... maybe because its at 91?

I thought we saw dyno numbers from just changing the mufflers, and the gains were WELL more then what we're seeing here.

H3llphyre, We tested the mufflers and saw very little difference at this power level. Without a doubt the tune would have been better had it been set up for 93. Brian did a great job setting it up for 91.

Radz, You are correct. The further back you go in the system, the less problem there is keeping the system downsized.

Nick

The gain from the tune is pretty typical. We were limited by shop temperature. We were seeing IAT's between 110 and 120 all day which limited the timing to 20 degrees. We made some pulls around 9pm and got the IAT's to 95 for the first couple pulls and were able to get 22-23 degrees of timing in it but were still limited. The exhaust and CAI leaned the car out a lot from stock so the fueling wasn't too far off by the time we started tuning.

See, other people are seeing a richness from CAI... weird.

What will the new heads do to the cars MPG?

What will the new heads do to the cars MPG?

head-ERS.... not heads. And, IMHO, it should improve MPG as long as you don't have a lead-foot.

What will the new heads do to the cars MPG?

Anything that increases engine efficiency (typically allowing more air in and out) SHOULD improve fuel economy, if you don't drive it like you stole it. Even then, it should get better gas mileage when compared to flogging it before the mods :)

I think everyone has the wrong idea here. I've seen about 20 threads about this. There is NO WAY you're going to make the G8 get 35mpg, or even average 30mpg with mixed driving. So stop trying.

How much louder than stock is it with the stock mufflers?

It's very quiet actually.. Got a nice growl to it when you step on the loud pedal.. You can't hear this car pull up to the shop.. Unless the fan's are on... i think the performance you get w/ the refinement of the car.. they compliment each other fairly well... the 2hp loss w/ the muffs the dyno is the "only" place you'd see it... We tried to be as fair as we could given the weather condition's.. car was on the dyno from 12pm to 10pm last night.. trying to get the weather to co'op was quite frusterating.. esp considering the potential of the car...even w/ the 91 octane... I'm seriously contemplating buying one.. that's how impressed i am w/ the overall build quality and perf. of this car...

He stated on the first page.... "The cats do have an EO number but the system as a whole is for off road use only.."

Wow! 39 hp & 40 tq to the wheels for just the ARH Exhaust! Nice...... Then even more with a CAI & tune......

These headers are going to be nice......

Can't wait to pick up my car tomorrow! The gains from this are sweet! Nick has been great i can't say that enough... brian at kaltech was awesome too! Supercharger next?

So, um, when will these be available? I just looked at the picture again and got excited (I'm easily amused I guess). Any idea on pricing?

I am glad I held off on getting the Magnaflows. I hope there will be some intro group purcahse for these headers.

Neil

Price man, PRICE!?!?!?

Nevermind, re-read other post...

No exhaust is going to give you 30 whp, none!!!! And mustang dyno's are known for being the most inaccurate way to messure hp. Dynojets are far more realistic in terms of power in the real world, that's a fact especially by all the dealers switching to the eddy-type dyno jets.

will these throw codes w/o tuning?

will these throw codes w/o tuning?


With any header system, a good tune is your best insurance to prevent a CEL while optimizing performance. I will say that thankfully it's pretty rare to get a CEL without a tune with an ARH system.

Nick

what is a CEL?

The system as a whole designed for off road use? I don't know much about that but if I got the headers I wouldn't be able to drive around normally or pass inspection?

That is good news Nick. I had BBK ceramic coated headers on my 96 z28. Even with the egr connected and new egr valve I had codes thrown (insufficient flow). :whine: I know, a tune could remove it but I never got around to it.

With just looking at the ARH unit, it is a 1000x the quality of BBK. It may be a long time before I can purchase this header system, but you have a customer in me. I am very happy that this system is complete to the stock mufflers. That is the perfect set up for me. You guys nailed it. :)

Nick, the set up on my LT1 had (I guess) an external egr system coming off of the headers on top. Where is the egr system in the G8? Thanks for the help. :us_flag:

which other companies are expected to release headers for our cars in the future ?

The system as a whole designed for off road use? I don't know much about that but if I got the headers I wouldn't be able to drive around normally or pass inspection?

Off road use typically refers to them not being able to pass emissions (visual inspection) in every state, starting with Cali and not having a carb number.

Some states, if I remember correctly, prohibit messing with the cats at all. So, if your stock cats aren't on there, you would technically be in the wrong, even with a set of hi-flows or whatever.

It's pretty much a disclaimer that a lot of parts manufacturers use so no one can say "Hey, you didn't tell me that my local county was going to not pass me on inspection with your stuff."

Nick, the set up on my LT1 had (I guess) an external egr system coming off of the headers on top. Where is the egr system in the G8? Thanks for the help. :us_flag:

99% sure the LS motors (at least the later ones) don't have EGR. Unless I completely missed something on the build I'm doing now for a different car.

I don't know much about these though, I'm an LT1 guy too. But bolts are bolts, so I'll put it together for the guy regardless! ;)

I can't wait to get these installed and tuned....(thanks Nick (ARH) and Mike (New Era Performance).

can somebody please pm me a price over here !

Any sound clips of this exhaust yet? I am very interested in hearing them.

$1705.00 plus shipping from New Era.

Thats a pretty decent deal for these headers considering the piping goes all the way to the rear muffles.

The price is similar but you need to contact them for the exact price.

Is the active fuel management more noticeable with headers?

I assume the kit would come with all the necessary O2 extensions.

Does American Racing have any kind of warranty on the cats? I had a problem with one of the cats on the kooks system on my '07 vette, luckily they replaced the cat no problemo.

Panther8, If you have a problem with our cats we will replace them. I will say that our cats have withstood the test of time with hardly any defects to speak of.

Nick

Thats exactly what the owner of a well respected muffler shop said around here...but he was being honest saying that it looked like a pretty labor intensive job..he would have to see install directions before he quoted me on a price....
I am scraping up pennies for this system as of now..

Headers are on the way for me, I'll post up detailed pictures and the gains they achieve. Cant wait! Maggie + Rotofab + AR Headers = Jail.


:)

Flash99, I thought that your sig needed a ARH! Sweet, hook us up with the info!

Do you have any installed pictures of the Headers? I would like to see how close everything is!

Would also like a sound clip if possible...

A.R. Headers

I'm in CA and would love to have this set up. I know it's not legal here but with the engine cover in place would the header still be easy to see? Would it pass the sniffer test if they failed to see the headers and cats? I have yet to have them actually look at the cats. If they did what about taking off the factory heat sheilds and weld them on to make it look factory? As you can see I'm searching here for a way to make this work. Any ideas out there?

When I had my 99 Camaro inspected the guy just plugged the car up to the computer and didn't even bother to look and see if there was anything done to the car. I had a cam, long tubes, no cats and only 2 of the 4 O2 sensors. But, I had it tuned. The guy up front said if it doesn't throw a code on the computer it passes as far as he was concerned.

One other thing, I can't remember if I asked this earlier or not but, will the headers fit on the GXP with the LS3?

LOL As I was posting this I got a PM about this question. It looks like I'll have to wait until there is a GXP to test fit before I'll know.

I'm hoping mine come in tomorrow, as soon as they are here, they will be installed, and I will be off to the dyno next Monday. I'm hoping of a 35RWHP gain.

A question for American Racing Headers:

Do the catalytic converters on this system produce the same emissions result as the OEM cats? In other words, would I expect to get similar sniffer test results with your system as with the OEM exhaust system? (All other things being equal, and recognizing that a chip tune might be in order.)

Mine will be installed Mon! I can't wait to drive Tigger around with his "growl" unrestricted! Will be well worth the ride to New Era in Rochester, NY and a lot more fun on the ride home. I will be sure to note any fuel changes on the way back

Whatca think about the voiding the engine warranty jus curious...I dont know If i should do cat back or headers

Jawdrpn, A header system will not void your powertrain warantee. I can assure you of that. Is that something you were told?

Nick

Jawdrpn, A header system will not void your powertrain warantee. I can assure you of that. Is that something you were told?

Nick

I tHINK there was some speculation on a thread on here about it..
IMHO the way the sales contracts are written with legal mumbo jumbo protect them alot more than us...and when I asked about mods during my sale.the guys said um dont realy recommend it will void the warranty...so even if not true the general attitude is it would be an up hill battle.. and the Dealers looking at any op not to cover something . I am just cautious...I have 2 months of time to save for the Headers ( there awesome) and some time to research more..

I will be doing install soon on mine and test emissions both ways. If it were to effect warranty it should only effect exhaust/cat warranty due to those components being changed. As long as headers are installed correctly/professionally it would not effect any other components. I have see the dealer try and say the extra HP caused failure and once the zone office phone # was blown up a few times the warranty repair was performed. Bottom line, it is a performance car that is going to be modified in some way shape or form. If it were not we would all be driving cars that got 40mpg. Charlie

Here's some more installed pics! Note how well the exhaust system fits into the framework of the car. Nick and his crew did an awesome job!

I cant wait! Mo power, Mo power, Mo power. I see some new low ETs coming up.

Yea....The gearing is really messing with our ETs Charlie. I was thinking along the lines of a around a 3.27. It would give us more launch, but we'd still retain some great top end. But that will probably be close to last on the list.

I dont think its gearing. For the track I will have about a .5 - 1 in taller tire so my rpms drop through the traps. The torque converter will me a HUGE gain. By allowing the car to get to its TQ band/rpm range quicker Tigger is going to be a full blown TIGER! Talk to Mike about this. Charlie

Ok Charlie...Will do

So... any drone out of these at highway cruising speeds?

Any louder than stock with the stock mufflers?

Junior, You are correct. The system starts off at 3" and continues that way till it gets past the X-pipe. After the X-pipe it reduces to 2-1/2" and continues to the rear where it connects to the factory mufflers.

LMAO!!

Here it is guys. As you can see these are long tubes and are made to bolt directly to your factory or aftermarket mufflers. I've only road tested thus far and the car sound pretty good even with the stock mufflers. It's quiet at idle but sounds good when your motoring through the gears. It may be a bit tame for some but I believe everyone should hold off on mufflers till they hear the system with stock mufflers. I believe for some this may be the perfect set-up.
We will dyno test and tune tomorrow as well as check the efficientcy of the stock mufflers. Hang in there as we bring more info your way. Thanks.

Sweet! I'll be in Cleveland all week again, but will get them put on maybe over the weekend.

Just ordered the Kooks mufflers from Maryland Speed.....So as soon as they come I'll get them on with a sound clip. I haven't heard back from Corsa yet on testing for them,. and I have to go back to work Monday......Hopefully I can still get Tigger out to them for testing. Someone will get a good deal on what ever muffler system I like the least. ;)

I got first dibs!

Ok, I guess I'm 2nd to Charlie again.

You are closer Ray, so once Jay decides, go get em! I just want sound clips of both.

I have way too much drone with the axle backs I made. I'm close to making a jig for these anyway. I might experiment with a couple different mufflers.
Nice to have a access to a muffler shop.

Get me the degree like we talked about and I can get the bends.

I've already have access to all the mandrel bent stainless I need. When I do the headers, I'll draw it all up, and send you the info.

so could i use these with a Corsa catback? without cats?

so could i use these with a Corsa catback? without cats?

Whats UP. Yes. The whole cat thing is up to you. You need to get it tuned for the headers and cats/no cats regardless. The axle backs will bolt up to anything.

But the ARH system comes with cats, right? Without them the length of the pipe will be different, no? maybe they sell 2 different systems, with and without with the withouts having more pipe?

Yes sir. It is a length of pipe.

I went from stock to SF's H-Pipe & AxleBacks. Now from what I can
tell from some of the online videos the ARH's + Stock Axlebacks are louder & more 'raw' sounding than my current setup right?

Anyone TRIED the ARH's with some SF's AxleBacks to compare? I'm
wondering if it'll be 'nice' loud or an insanely-please-turn-it-off-my-ears-are-bleeding loud

Also the above has me a little confused - so DO or DON'T they offer
a completely cat-less version?

Thanks!

Anyone TRIED the ARH's with some SF's AxleBacks to compare? I'm
wondering if it'll be 'nice' loud or an insanely-please-turn-it-off-my-ears-are-bleeding loud

Also the above has me a little confused - so DO or DON'T they offer
a completely cat-less version?

Thanks!

Get the cats. If you have you stock muffs try both. The ARHs X is what gives you the sound you want.

The ARH cats are the best available from everything I have ever seen .

ARH does offer catless, as a matter of fact I have the catless ARH's. I would say if you live in a state with no inspection, go catless.

Do you have a sound clip without the cats on the stock mufflers ?

I'll try to get one posted this week.

Still waiting ...

Has anyone gone with the ARH system and not done a custom tune? If so are you having any trouble codes or check engine lights show up? Or does anyone know if this would cause any check engine lights to appear?

You will get CEL's if you get the hi flow cats. The sensors read temperature climb rates and the stock cats are sinked to the sensors. Adding the hi flow cats allows the cats to come up to temp more slowly because they are in fact less restrictive. The sensors read this as a fault and send the CEL. The opposite is acutually true, in that they are just more efficient.

Tune or no tune you must tell the tuner you have hi flow cats with the headers. They will simply eliminate the ECM from allowing the sensors to read the cats. Problem then solved.

Also, BTW, I have the ARH and cannot say enough about them and their customer service. I installed my own. The quality is top notch and they will answer your questions and provide you whatever you need if you have any issues, which you will not. Just follow the instructions and you will be fine.

Does anyone know if the catalytic converter has to be removed to install these headers? I'd like to get a set but in FL you may have legal issues in transferring ownership of your vehicle if emission controls have been removed or tampered with, and reduce saleability if new owners can't get clear title. Please advise, thanks

The stock cats get replaced with high flow cats. Just keep the vehicle, or put it back to stock. I have everything I've removed from my G8 except for the stock mufflers.

G8GTlawride, We really appreciate you sharing your thoughts on our system. We'll continue to work hard and provide the best system to G8 owners. BTW, I have an 09 on order. Can't wait.

I am in Florida as well. There are no legal issues with selling a car, period unless some local authority does. There are no inspections for such sales either. Get the headers.

Your very welcome.

I have seen firsthand the problems associated with the buying/selling of vehicles in Florida with catalytic converters and air pollution devices removed. I have seen vehicles lose value on resale as a result because dealers will have to spend money bringing it back to OEM just so it is legal for them to sell to the public; as a result you can get beat up in a trade. They did away with inspections but still on the books are some regulations about removing related OEM equipment. Check out Florida State Statutes 316.2935, in part here:

Title XXIII
MOTOR VEHICLES Chapter 316
STATE UNIFORM TRAFFIC CONTROL

316.2935 Air pollution control equipment; tampering prohibited; penalty.--

(1)(a) It is unlawful for any person or motor vehicle dealer as defined in s. 320.27 to offer or display for retail sale or lease, sell, lease, or transfer title to, a motor vehicle in Florida that has been tampered with in violation of this section, as determined pursuant to subsection (7). Tampering is defined as the dismantling, removal, or rendering ineffective of any air pollution control device or system which has been installed on a motor vehicle by the vehicle manufacturer except to replace such device or system with a device or system equivalent in design and function to the part that was originally installed on the motor vehicle. All motor vehicles sold, reassigned, or traded to a licensed motor vehicle dealer are exempt from this paragraph.

(5) Any person who knowingly and willfully violates subsection (1) shall be punished as follows:

(a) For a first violation, violators shall be guilty of a misdemeanor of the second degree, punishable as provided in s. 775.082 or s. 775.083, except that a motor vehicle dealer shall be guilty of a misdemeanor of the first degree, punishable as provided in s. 775.082 or s. 775.083.

(b) For a second or subsequent offense, violators, including motor vehicle dealers, shall be guilty of a misdemeanor of the first degree, punishable as provided in s. 775.082 or s. 775.083. In addition, the Department of Highway Safety and Motor Vehicles may temporarily or permanently revoke or suspend the motor vehicle dealer license authorized pursuant to the provisions of s. 320.27.

(7) The Department of Environmental Protection shall adopt rules that define the specific wording of the required certification and the circumstances under which the certificate is not required. In addition, the department shall adopt rules as necessary to conform to requirements of federal law, to establish procedures to determine compliance with this section, including specifying what tampering activities constitute a violation of this section, and to provide for exceptions and waivers. For those rules applicable pursuant to subsection (1) to licensed motor vehicle dealers for certification by visual observation, the air pollution control devices or systems that shall be included in such certification for motor vehicles dated model year 1981 or later are the catalytic converter, fuel inlet restrictor, unvented fuel cap, exhaust gas recirculation system (EGR), air pump and/or air injector system (AIS), and fuel evaporative emissions system (EVP). The department may by rule remove or add devices or systems to this test if justified by developments in air pollution control technology or changes in federal law.

The way I read this is that if the OEM cat is removed you cannot sell the vehicle in FL except to a licensed dealer. Am I missing something? I have seen the emission certificates that dealers have to provide during the registration process.

It doesn't seem to provide any penalties for the act of removing the cats or operating a vehicle with different cats or no cats installed for that matter, just illegal for anyone to sell it in that condition except to a licensed dealer. At least that is how I read it. I guess you can always sell it in another State. LOL

As G8 Ray said, he is keeping the stock cats if needed. Seems like good advice. It would be great if an attorney or car dealer could weigh in on this subject. I will buy a set as long as it isn't going to come back and bite me in the ass. LOL

Here is how I look at it. If you plan to trade the car in at sometime you would be better off taking the hearders off and selling them anyway as you will get no extra value from the header durring a trade. The same would go for a private sale unless you have a buyer that wants the headers and if that is the case I would doubt that they would bring up any legal issues with the sale.

Your missing a lot! First, if you trade, your getting hosed no matter what you have on your car. So, if a dealer TELLS you what you cite here about putting it back to stock, you are getting hosed again! Twice! You might as well just give them the keys and say thanks and ask for a reach-a-round! Please tell us what you have SEEN FIRSTHAND in regards to selling any car with catlytic converters and air pollution devices removed. Did you trade in a car and then go back to review the problems the dealer had or did they just tell you that when you went to trade so they could de-value your car more?

Bottom line, DON'T TRADE and you CAN'T get beat up.

Not trying to bust your B... but we do not have inspections here. There are FSS that have been on the books forever that are NEVER used by ANYONE. Unless the State of Florida brings back the annual inspections, have fun with the car and mod the hell out of it! And when you are tired of it DO NOT TRADE IT UNDER ANY CIRCUMSTANCES! YOU WILL GET HOSED!

Paulpi, We worked very hard to build a system that maintains all emissions hook ups, has cats and delivers mind boggling performance. You may even see an increase in your fuel mileage which isn't uncommon. Modding isn't for everyone. But for those wanting to take the fun factor to a whole new level, you just can't beat a great set of A.R. Headers.

I can attest to that!

Thats what I should have said the first time.

I am aware they have done away with individual inspections...I live here. The inspections you are referring to are not the same same thing as this statute above. My "firsthand experience" I am referring to recently when I was looking at a Ford Taurus to buy for work at a dealership, who said he couldn't sell me that one because the cat had been removed, and he could only sell to another dealer. Also, I go to public auto auctions on occassion over in Tampa to look for deals, and sometimes the vehicles are being sold with emission controls removed, and the auctioneer can only sell them to licensed dealers, not public bidders. I understand they are sold to dealers because the dealer is required to put them back to OEM. This brings the value down on the auction prices. The FSS I cited above is not an old statute that is not being enforced....it is being enforced daily...but not they way you are thinking.... it is enforced on businesses, such as car dealers and car auctioneers, etc., with whom the DMV investigators can make regular inspections on and when the registration paperwork is turned in....they have to turn in emmssion affidavits. I understand they did away with individual inspections regarding pollution output 3 or 4 years back, and that you are not going to get stopped on the street and get a citation....I am talking about when the vehicle is resold here, there are specific laws that dealers have to comply with during the sales process. Read the statute.

I just wanted to know if anyone else in Florida has had any experience with this issue and how it has affected them on mods that have been made. I am all for being able to mod the car...I'd like to buy a set of headers, I just want to look at any angles that may affect resale value and what I can do to minimize any downside if I need to resell after installing them.

To address your concerns, the best thing to do is to keep all your original components and switch back to them when the time comes to sell or trade in. As hot as our G8 systems are, you'll have no problem transferring ownership to another G8 owner.

^What he said! Keep all factory pieces! Buddy of mine had a fbody that was rearended. The insurance would not pay for aftermarket stuff, so we swapped them. We were lucky that all we had to do was put the factory parts in the trunk! :) It is a hassle, but money isn't easy for me!

Which size are most people buying? Is the larger size for a particular purpose or setup?

1 7/8" is for if your adding a supercharger or big cam also.
1 3/4" I believe is good up to about 500HP

That's what I figured. The problem is that I am sure that I want to use these headers, but I have not decided if a supercharger is in my future or not. Will there be a performance cost by going with the 1 7/8" and end up not adding boost or cam?

Supposedly you lose a little tq down low but pick up some hp up top with the 1 7/8.

Having the ARH headers installed tomorrow back home and today here Aug 12th!! I CANT WAIT to see what kind of gains I get out of this system coupled with Vararam CAI, HP Tune and Magnaflow Axleback!!! Hell, I only put 2000 miles on my car when I got it on my last R&R so when I go home to her this time it will be like turning the keys to a brand new car all over again LOL!! Plan to go first thing and put in some Mobil 1 since she has right at 3000 on her now and then lookin forward to going out and finding a few friendly runs before I have to return to this hellhole!! Ill post up dyno numbers when I get home on the 27th!!

I assume the torque loss is just in comparison to going with the smaller size and not compared with stock right? Also, I wonder if it will really be that noticeable considering the torque management on these cars.
