Difference in mid pipe Is there a power difference in using the bbk longtube headers with the catted shorty x pipe or the uncatted x pipe?


  • Uncatted might be a little louder but you could have problems with the engine light coming on and you have to tune it a certain way

Will these work with pypes catback exhaust?


  • When installing this Shorty X-Pipe along with the required BBK Long Tube Headers, you should have no problem bolting the x-pipe to the Pypes catback exhaust. Hope this helps!

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?


  • 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

    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.

    Sound, Power, Amazing!

    Had these installed with a set of BBK long tube ceramic headers. The sound is awesome, the power is noticeable, and it is needed for the long tube headers. Don't forget to get a tune for both the headers and x-pipe.

    Took it to a shop to have the BBK long tube header, BBK cat sorty x pype, SR lowering springs with 19" wheel kit from AM, SR panhard bar installed and needing to re-balance the wheels after lowering it with a total of $720. End result it sounds and looks like a beast!

    The BBK Long Tubes look like a factory install. They are above the frame with no clearance problems like some brands. Look and perform great!

    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

    Great company

    Great looking product, but the catted x pipe did not fit well, I had to bend the hangers and the pipe to hook it up to the headers. Took an extra 45 minutes to install and had I not had help, I wouldn't have been able to install it myself.
