    About to pull the trigger on purchasing solo's high flow cats but before I do, do they bolt right up to the stock exhaust after the cats? Just making sure.

    I bought these and then discovered I cannot use them with my current exhaust. Yes, I am getting Kooks long tube headers in the near future but will be connecting them to a non-Solo catback exhaust system. I thought I could modify these to work but then realized a solution where I will reuse the...

    I've had the Solo HFC and Mach balanced system installed for a few thousand miles without any issues. The kit did come with the the O2 extenders so those are installed. I recently had the CEL come on with the P0430 code. I reset it and a few hundred miles later it came back on. On this...

    Solo Performance exhaust systems are a huge step forward in exhaust technology. Solo uses their J mufflers to give you an amazing muscle car sound second to none and they do it without creating unwanted drone. That's right, drone free muscle car sound that turns heads. They have several kit...

    I have for sale a used set of 1 7/8" Kooks LT headers in great shape and a full solo cat-back exhaust. The solo kit is *I believe* the Mach kit that has been cut and re-welded to fit the Kooks headers. This is a non-cat system and sounds incredible. This will be sold with all necessary hardware...

    I just installed a pair of solo axlebacks on my 09 GT and while I had them out I weighed the stock mufflers and solo j pipes to see if there was any considerable weight savings and this is what I found. The stock rear mufflers weigh 20.6 lbs each and the solo axlebacks weigh 12.8 lbs each. This...

    Hopefully the title will get some attention and I hate to beat a dead horse :judge: or should I say a Mustang. Ok, that was bad. But I am looking at getting a CAT back system on my stock GT (with rotofab). I have searched the forums, you tube and talked to installers. The problem is, as you all...

  13. Exhaust Tech
    Saturday I ordered a cat-back system for my gt. it was the solo Mach shorty. Any good reviews on it? I personally am a fan of volume coming from the exhaust. Let me know if you think it's too loud or not. How quickly do they ship? And how good is the quality? From all of the clips I've seen, I'm...
  14. Buyer / Seller Feedback
    I just wanted to share a experience I just had with Jeff at Solo-Performance. I recently ordered and installed a 3.5" Axle Back kit for my 2009 G8 GT. I called Solo directly and placed the order through Jeff. Everything was shipped quickly and packed with quality packing and included some nice...

    I just wanted to share my recent experience with SOLO. I've owned my SOLO exhaust for just over 2 yrs and have about 14K miles on it. I recently had an issue and brought it to their attention. They responded immediately and quickly rectified a situation that would have been easy to pass off...

    DEAR G8rs... OK.. Been reading the exhaust posts for like two days now, and am no further in my search than i was. How I got here. I found the seals at the muffler flanges were leaking so I figured I would take them off and put new ones on. Well no aftermarket place even has a listing...

  18. Wanted to Buy / Trade
    Looking for the Solo Axleback system with the 3.5" S/S tips. I also may be willing to trade my Magnaflow #16883 axlebacks in lieu of a straight up sale if you are interested.
  19. Solo Performance
    maybe this is a dumb question, if so.. im sorry lol but for the first 5-10 minutes of driving my solo axlebacks are pretty much silent, when the engine temp rises and the meter is up about half way then it gets loud.. does this happen to anyone else?
  20. Exhaust Tech
    Just purchased my 08 gt and I am a little disapointed in the sound. I was thinking about doing the DMH cutouts, but was wondering if anyone has run into any other problem besides the rattling noise? Feel free to post your opinions. Thanks Josh
