    Increases Overall Performance. Add even more horsepower and torque to the rear wheels of your GT Mustang with a BBK After Cat X-Pipe. A BBK X pipe will greatly improve your pony's exhaust flow to increase overall performance. This BBK x-pipe is designed to be used with BBK's shorty headers or the factory manifolds.

    Race Car Growl. This free flowing BBK x-pipe for the 2011-2014 GT Mustang's not only increases power, but it also adds a crisp raspy, race car growl to the sound of your exhaust with its modern "X" crossover pipe design.

    Compatible With Stock Cats. The BBK GT X-Pipe bolts up directly behind the factory catalytic converters with no cutting required saving you time and money. By reusing your stock catalytic converters you ensure that Mustang is smog-legal.

    Durable BBK Construction. BBK's X-pipes use a free-flowing 2-3/4" diameter CNC mandrel bent aluminized tubing and a merged X crossover to improve flow. It also features OEM style hangers that attach in the stock locations for a perfect fit.

    Application. This BBK After Cat X-Pipe is designed to be a direct bolt-on for the 2011-2014 5.0L GT Mustangs with either aftermarket short tube headers or the factory manifolds and a dual catback exhaust installed. Reuse the stock Catalytic Converters.Installation Note. When installing this X-pipe on a BOSS 302 Mustang you will loose the functionality of the factory Side Exhaust pipes.

      BBK X-Pipe

      The BBK X-Pipe was of a good quality, and I like the badging on the pipe. Installation was a bit tougher than I expected, especially trying to cinch it tight at the drive side cat pipe. Also, if you have not had any exhaust work done prior, the stock clamp bolts at the catalytic converters are on the top, and were very hard to loosen with a quarter inch ratchet; Nothing bigger would fit. I do not notice much difference in sound with the stock mufflers, but that should change once I finish with the exhaust upgrades. Oerall I think this is a very good product for the price.

      Not bad, not bad..

      It has a aggressive raspy sound under hard acceleration and cold starts..But i also have resonator deletes and a no muffler axle back exhaust..I just wish it was a little bit louder though..So overall not bad for the price!

      Bbk after cat x

      Delivery was quick, and it bolted right up with ease. Have to get the oem cat to x pipe just right for no leaks. Like most people state it kinda silences a bit at idle. Driving though another story specially when wot. Thanks AM AND BBK.

      Perfect fit

      Perfect fit with everything else stock. However, I was kinda surprised that is was more silent compared with the stock H-pipe, especially on low rpm's.

      Extremely loud! Sounded great. I added this to my long tube headers with a Borla exhaust. Worth it! Highly recommend it.

      BBK X-pipe

      At first you're just confused on why it doesn't sound crazy different but once you step on that pedal it's got the right flow and right tone other than the bolt being pointed straight up to the frame from the cat clamp I'm happy with it.

      Direct bolt on !!

      I bought this x pipe, along with the cat delete pipes!! Everything fits like factory! And has the aggressive sound that I'm used to on my mustangs! BBK has always had good quality parts , that fit, for a good price! Also like everyone says, it is a pain to get factory bolts off. I actually snapped 2, and that was easier than getting the other 2 , wish all would of broke off!! Very happy stangbanger once again !!

      Just Awesome!!!!

      I bought the BBK Cat deletes about a year ago and was running them with no mufflers (still have the resonators). The exhaust was loud and sounded pretty good, but a little obnoxious at WOT. I purchased this x-pipe and couldn't be happier!!! I love it. It smoothed out the exhaust sound, made it more throaty, not so raspy. I can feel a difference in the performance too, woke that thing right up. Fitment; I had a shop install it and weld them to the Cat deletes, cost 50 bucks!!! Well worth the time and headache it saved me trying to get them to seal against the deletes. So now I am running BBK Cat deletes and X-pipe, with resonators and no mufflers, throw in the MPT Ghost cam tune, and it's music to my ears. Thanks AM and BBK!!!!!!!

      Good cheap mod

      Took no longer than 45 minutes, quieter at low rpms especially in cabin. Has a nice rasp especially on downshifts and fairly noticeable gains. If I had to say I'd find a local shop to buy from you're just paying for the brand name
