Default JBA Long Tubes

I thought id start a thread about the JBA long tubes. Another member on here turned me on to a seller on ebay who has a few sets on clearance. The price was too good to pass up so i bought a set. Here is a pic just out of the box. I apologize in advance, it will be weeks until i am able to install the headers, maybe someone else with more time will get there's on before me.



They came with the O2 extender and the flanges that i assume i will need to weld to my factory exhaust. I was under the impression that they "bolted up" to the factory exhaust. Looking at the pieces here, i dont believe that it the case. No worries, i have a welder, i can make it happen. Just a heads up for those looking for headers.

The headers are stainless, uncoated, I have not decided yet if i want to get them coated for underhood temps or just leave them. I can take more pics if anyone wants. Ill probably at least take a shot of the primary tube just after the flange.

1 3/4" headers are 1 3/4" OD measurement. I ordered the same header just now but Jethot coated.

I have them on, they are 1-3/4" I measured them because I had tricked myself into thinking I got 1-7/8"

Are you planning on coating them? If you get any snow and its your DD I would suggest it. 400 series stainless will mostl likely not rust through like aluminized or mild steel, but it will probably get surface oxidization if not treated.

I got mine ceramic coated for $200 I think it is worth it.

Bo - these really made an improvement, I got 20+ whp more @ 1500 rpm vs. without. Sound great at startup, and the interior note even at the loudest is not annoying at all (to me anyhow) - really good set for the price IMO.

Thats funny. in my profession we measure all pipe by the id. i guess you learn something new every day.

Boston. Thanks. I was the guy who suggested you get them coated in your thread. I don't get any snow here in the SF Bay Area but I plan on getting them coated anyhow. I just need to find the time

I recently found out they actually come from the factory in 4 finishes - nickel chrome plated mild steel 14 gauge, 409 stainless 16 gauge, silver plated ceramic, and titanium cermaic going from least corrosion/heat-resistant to most. I got mine coated by someone separately, but there was a guy who posted on here about buying JBA headers in the past and having them rust - I guarantee he had the mild steel chrome plated ones now knowing this.

good luck w/ them

lifted from LS1tech:
Tubing => specified nominal value refers to outside diameter (O.D.)
Pipe => specified nominal value refers to inside diameter (I.D.)

Interesting. I work in refineries with both pipe and tubing. Both of which we measure by the ID. That includes some sweet stainless that we use for process instrumentation. I wish I could take some pictures but that's a no-no out here. Too many secrets.

I don't think they have a mid pipe for their LT's.

In the past I have ran headers that weren't "smog legal" on other cars. What I did is weld cats on after the headers, usually magnaflow, and then take the car to the shadiest looking smog shop in town. In my experience, a lot of these shops are more concerned with getting you in and out and making a quick buck, rather than looking over your car with a magnifying glass. As long as you pass the sniffer. This is obviously just my personal experience. That is my plan with these headers.

Guess shops up here are more "legit" I guess...

Makes me wonder what the HP diff. is between shorty headers and Long Tubes?

No its just there are fewer shops per square mile, know what I mean.... If you asked enough guys you'd find the one or two who'll do it. But who wants to go thru all that? ya know?

I just happen to know who I can go to because of all my years of playing with mustangs.

edit - power difference... probably about 15-20 at the wheel. Not a big deal IMO. I havent totally decided on LTs on this car yet. I have them on my mustang and I'm not sure I want that issue on this one.
