Is it possible to use the long tube headers and x-pipe with the stock GT mufflers? Looking for a little rumble, but don't need it to be obnoxious.


Helpful (0)
  • Purchasing and installing the BBK Catted X-Pipe (05-10 GT w/ Long Tube Headers) and matching BBK long tube headers will be able to be used with the stock mufflers.


Will this go with my mac longtube headers?


Helpful (0)
  • The BBK Catted X-Pipe (05-10 GT w/ Long Tube Headers) will not work with the Mac long tubes. When doing long tube headers you want to match up the same brand mid-pipe as the header for proper fitment.


Can I use these with the pacesetter long tube headers and pypes violators mufflers?


Helpful (0)
  • When it comes to long tube headers we typically say to stay same brand between the mid pipe and the headers just because manufacturers design them specifically for each other. So if you tried to do anything other than a BBK long tube with the BBK Catted X-Pipe (05-10 GT w/ Long Tube Headers) you would most likely need to do some modifications. However, when it comes to the muffler, you can do whatever muffler you want, the muffler is not held back by the mid pipe or the headers.


Answer This Question

Axel back or Cat back exhaust. Will both Axel back or Cat back exhaust work with this? Im just wondering if a muffler shop would be able to weld some pipe to make it fit. Or would that not be optimal?


Helpful (0)
  • Yes this can be made to work with either and the right muffler shop can weld whatever you need. Most companies however make sure their parts align perfectly so going with one company for your whole exhaust setup is never a bad idea


Answer This Question

Would this work/fit a v6 with long tube headers? Would this work/fit a v6 with long tube headers?


Helpful (0)
  • YES. The midpipe will fit together perfectly with longtube headers with same ball connection fittings.


Answer This Question

o2 sensor extensions? Will I need to buy O2 sensor extensions? Just wondering if the stock sensors will reach the cats in their new position. i have an08 gt and I plan on going with the long tube bbk ceramic headers and the bbk shorty catted x pipe


Helpful (0)
  • You must have O2 sensor extensions to reach the cats on the X-pipe, but BBK includes them with their X-pipe. The alignment tabs on the plug may not line up with your O2 sensor plug so you'll have to cut them off. Just make sure the color coded wires line up when you plug them together. The plug is shaped so it only fits one way which should prevent plugging it in the wrong way.

    Excellent product

    Works in perfect harmony with BBK's long tube headers. The cats work too, no check engine light, just make sure you let the car fully warm up before you bury the gas pedal...i didnt one time and tripped the light and the code was "catalyst below threshold". Just erased the code and it never came back. Very good product, and American Muscle got it to me in just a few days. Excellent service!

    Oddly Didn't Fit, but Works Great

    I got the x-pipe from AmericanMuscle and the headers from another source, both meant for the 05-09 Mustang GT. After having a shop put the headers in, they found that the x-pipe had a larger flange that wouldn't allow it to bolt to the headers. The x-pipe doesn't look like the picture shown above, but what got me personally was that both products were meant to work with each other but didn't. I ended up calling AmericanMuscle, and they helped me through the process of having this problem fixed up. It ended up taking 5 days to get everything fixed/installed. All in all, the x-pipe and headers really brought out a sound I wasn't expecting. I've gotten compliments ranging from "sounds like an angry bear" to "this is what a real modern muscle car should sound like". Thanks for all the help AmericanMuscle!

    BBK Catted X-Pipe 05-09 Mustang GT

    I live in MIssouri and AmericanMuscle got this to me in 3 days. Free and super fast shipping, is there anything better? The install was pretty easy, of course, you need the BBK longtube headers and these will match up 100% it took a little over an hour to install the x-pipe and the included O2 extensions. And I did it by myself on jack stands. I noticed some differences, the sound... oh the sound! It gave my stang a whole new rumble (get rid of those huge ugly stock cats) and I got roughly 12hp gain on the dyno after the install. These were a perfect fit for my fully aftermarket exhaust (Longtube Headers, x-pipe, mandrel bent mid-pipes, and an axle-back)

    Quality workmanship

    With just a little tweaking, the catted x-pipe fit like it was supposed to. We had to slightly widen the header end to fit the BBK long tubes. Once tweaked, fit like a glove.

    Needs better quality control

    Made this pipe fit by heating and bending tubes because it was too narrow to fit up to the BBK long tubes. The rear of the pipe was also slightly bent down on one side but I managed to slide it into tailpipe by opening up the sleeves completely. Also had to cut off the hangers as they aren't used on my car. Also doesn't seem to fit with my Moroso driveshaft loop. Soundwise it sounds good not crazy, works well enough for me at this point.

    VERY disappointed. Needs expensive modifications.

    This midpipe was nearly 1.5" too narrow to align with the expensive BBK headers sold with it. The hanging brackets also had to be moved to go into the stock mounts. Since I had a pro shop doing the installation, it cost me several hundred dollars more than quoted. BBK products will not be purchased by me again.

    needed piece to have with headers

    Bought this to go along with my bbk long tubes. got cats because of inspection and I have neighbors, so I wanted it to be a tad quieter. I'll be honest, these cats are that much quieter compared to no cats at all, but still sounds great!Tthe whole x pipe is very well made, went on fairly easy, had to kinda stretch it onto the headers to get them on, so everything is nice and tight. I only wrote full day for installation because it was part of the header install, realistically an xpipe only takes about an hour or so. Great product, good sound, good price! Cant beat it
