kahmann Posted November 28, 2009 Report Share Posted November 28, 2009 I'm ready to buy my new exhaust and have narrowed it down to two choices. Any input on the two is much appreciated. JBA long tubes - 1 5/8" primary x 2 1/2" collector - stainless steel with titanium ceramic coating JBA off-road H-pipe - 2 1/2" inlet x 2 1/2" outlet or Kooks long tubes - 1 3/4" primary x 3" collector - stainless steel (coating unknown) Kooks off-road X-pipe - 3" inlet x 2 1/2" outlet There is nearly no price difference between the two. The JBA's would ship out of Summit and be here by Tuesday at the latest. The Kooks would ship out of Lethal and be here in a week or more. Other than that, I guess it comes down to brand, header size, and H vs X. Ken EDIT: I've also considered cutting my original x-pipe and re-using it with either set of headers.

08SGT952 Posted November 28, 2009 Report Share Posted November 28, 2009 I just added JBA Ceramic Shorties and a JBA Axel back with 4" tips. The fit and finish is excellent. The sound is really good. I don't think you can go wrong with either. Good Luck. Link to comment Share on other sites More sharing options...

Testing Seven Long-Tube Header Systems For S197 'Stangs http://50mustangsuperfords.automotive.com/...hooker-jba.html This is perfect man, thanks a lot for digging this up for me. Looks like the Kooks and Mac headers are neck and neck at the top. The gains are phenomenal above 6k RPM! Link to comment Share on other sites More sharing options...

Ken, I know very little compared to the rest here, but if long tubes were in my dreams they would be Kooks. Lg Link to comment Share on other sites More sharing options...
dave c Posted November 30, 2009 Report Share Posted November 30, 2009 Looks like I'll be ordering the Kooks from Lethal. Ken Are these long tubes going to be able to pass emissions? I've heard that long tube headers don't. Would love to do headers, but I wouldn't want to take them off to pass emissions. So whats your take on this? PS. Can't wait to see the car in Vegas. So put the hustle on it. Link to comment Share on other sites More sharing options...
kahmann Posted November 30, 2009 Author Report Share Posted November 30, 2009 ^ Hey man I'm working as fast as I can here! As for the headers, you're right, they won't pass smog (especially since I'll be running cat-less). The only headers that are CARB friendly are the factory manifolds and shorty style headers (like the JBA's that I just sold to Jim). If my car is still a street car by the time smog is due (about 4 years from now), then I'll just have to hope that my smog guy is still able to work his magic. If it's a track only car by then, I've got no worries. My only concern between then and now is a random inspection of any sort. That would cause me a tremendous headache.

kahmann Posted November 30, 2009 Author Report Share Posted November 30, 2009 ^ Thanks. I'm sold. Just ordered the Kooks long tubes with 3" collector, plus the Kooks off-road x-pipe (3"x2 1/2"), both with the JetHot 1700* sterling silver coating. I ended up ordering from a shop called Maryland Speed. They came recommended by another guy on TS and had the best deal on the Kooks stuff, including free freight within the lower 48. I'll get photos up once this stuff arrives. Thanks again for all the input. Ken Link to comment Share on other sites More sharing options...
kahmann Posted December 15, 2009 Author Report Share Posted December 15, 2009 The x-pipe arrived today. The headers are scheduled to arrive December 16th. However, they coated and shipped 2 right side down pipes for the x-pipe. I've emailed requesting that a left side pipe be sent out asap. I'll get pics up tomorrow. The coating is really a whole lot nicer than I expected. Ken Link to comment Share on other sites More sharing options...

kahmann Posted December 17, 2009 Author Report Share Posted December 17, 2009 Very cool. Where does this attach? To the backside of the existing x-pipe? Or does this replace the x-pipe and attach right after the cats? Ken Link to comment Share on other sites More sharing options...
2007_Shelby_GT Posted December 17, 2009 Report Share Posted December 17, 2009 By all appearances, it attaches after the x-pipe. I was reading in the QA with Amy forum and that's what it sounds like. Only drawback is that it's very low according to a couple of folks. I'm on the fence with this one, but it does look great and reminds me of the GT350 of old!

kahmann Posted December 17, 2009 Author Report Share Posted December 17, 2009 I'll have to look into this a bit. I like the look a lot. Just have a few questions, 1) does kit include block off plates for rear fascia, 2) are rocker panel plates included, and 3) is there any issue attaching to aftermarket x-pipe? I'd want to bypass the muffler completely, so I also wonder if Borla would sell just the side pipes themselves, sans muffler. Ken Link to comment Share on other sites More sharing options...
2007_Shelby_GT Posted December 17, 2009 Report Share Posted December 17, 2009 Nope, no block off plates for rear fascia - Bummer, guess you'd have to fashion your own. According to what I've read, no heat shields for the rocker panels either. Someone wrote that they made their own, but never installed them after they discovered that it wasn't an issue. I guess if the pipe diameter was the same as aftermarket pipes, that wouldn't be to much of a problem welding or coupling them together. Jeez, one mod leads to another!
