Increases Overall Performance. Add even more horsepower and torque to the rear wheels of your GT or Bullitt with a BBK Catted X-pipe. A BBK catted X-pipe will greatly improve your pony's exhaust flow to increase overall performance. BBK's in-house dyno-testing has shown solid gains of 12 to 20 horsepower.

Race Car Growl. This free flowing BBK x-pipe for the 2005 to 2010 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.

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. And features High flow catalytic converters to provide a significant horsepower increase over the restrictive stock cats.

Application. This BBK Catted X-Pipe is specifically designed to fit the 2005-2010 GT and 2008-2009 Bullitt Mustangs with either BBK's 1612 Series shorty headers or the factory manifolds and a dual catback exhaust installed.

I have a 05 GT, with Roush supercharger and tune. I want to replace the H pipe with the BBK Catted X-Pipe, I live in south texas and have to have the cat's for Ems. at present I have Shorty Cer headers, and Roush cat back exhaust installed. the question is will I have to have the Roush tune updated for this install or is it just plug and play?????

  • Hi, A retune is not required for the installation of this x-pipe.

Did anyone install this on 2010 V6? Just want to make sure it will fit. Thank you.


Helpful (0)
  • The BBK Catted X-Pipe (05-10 GT) will not fit on the 2010 V6 Mustang. The piping size is 2.75" whereas the BBK Catted X-Pipe (11-14 V6) item #56232 ( has a piping size of 2.5" which is the stock size of the piping for V6 Mustangs for 2010 models.


I have stock headers and fr500s axle back . I like the way it sounds, but looking for more sound! Where i live i cant do off road. Now, these catted bbk will keep the american muscle car tone and rumble , but its gonna be more louder,or the tone will change? And also after install i m gonna have check engine light ? I dont have a tuner and dont want one. Thanks!!


Helpful (0)
  • When you are swapping your stock mid-pipe for an aftermarket one, the sound will change especially with this mid-pipe since it is an X-pipe. This X-pipe will give you more of a raspy sound. So yes, your tone will slightly change as it will a more aggressive growl to your exhaust. Also, as you can see in the picture before and after the cats there are O2 bungs in which to plug in the O2 sensors. With the O2's properly installed into the bungs, you should not have a check engine light appear. This will also not cause you to have to re-tune your vehicle.


I have stock exhaust with pypes muffler delete. Will this fit? Or do i need cat backs for it to work? Thanks


Helpful (0)
  • The BBK Catted X-Pipe will work with your stock exhaust, and the installation will not require additional components.


Does this have ceramic or metallic cats?


Helpful (0)
  • The BBK Catted X-Pipe uses ceramic Cats.


I have flowmaster hushpowers and i like the sound, but i would like it to be louder and have more rumble when downshifting. Will this xpipe with the cats give the sound i am looking for? Used to have an 89 5.0 with o/r x pipe and flowmaster 2 chambers, i understand its not going to be quite that loud or sound exactly like that, but that sound tamed down alittle is what i am looking for! Am i looking at the right product?


Helpful (0)
  • The BBK Catted X-Pipe (05-10 GT) will help with getting that sound you are looking for. However if you want more rumble I would recommend the BBK Off-Road X-Pipe (05-10 GT) item number 56120.

    Perfect tone

    I chose this x-pipe to replace my Pypes Race x-pipe for two reasons: pass AZ emissions and my Pypes Race x-pipe was honestly a little loud when rolling the throttle at low rpm in 5th gear. I had my local Ford Dealer install it, so I can't comment on the installation. But the tone is awesome and it's nice to finally pass emission but still have a little heat coming from the pipes.

    Great Mod!

    I absolutely love my BBK catted x pipe. It gives the car a great growl that is raspy but not too bad. My setup is BBK catted x pipe with flowmaster outlaws, car is loud, but not so loud that you would get pulled over. Install went great, had a little trouble getting the o2 sensor unplugged on the passenger side located on the manifold. My recommendation is to access this from the top side instead of bottom. Would definently reccommend this product!

    Prior to having the BBK Catted X-Pipe installed, I had the SLP Loudmouth Axle-Back Exhaust. They were pretty decent, but lacked any real tone at low RPM's. I drive my car with the goal of getting the best fuel economy possible, so I am always under 2500 RPM. Adding the BBK has allowed my V8 to make a statement at low engine speeds! To me, it sounds quite a bit like a 1960's muscle car, as the exhaust rumbles in a similar fashion unless you get on the throttle. When on the throttle (15-20 at most) it starts to sound like the GT that I am most familiar with at my local show. Definitely has me stoked for when my local weekly car show starts up! Cannot wait to bring my new GT in. Thanks American Muscle for providing me with such a great product!

    Great product, great sound

    Ok I know probably a lot of you would say "what is he thinking?" I recently cammed my Mustang 2008 GT M Thumpr cams it sounds great but having a straight pipe or Xpipe offroad was really loud. It made my home shake literally. And to be honest where I live I have to cross the border a lot and getting with the CBP everytime I needed to cross back was not something I was willing to do. The good thing is that now I can have the rough sound of the cams but without the super noise. I really recommend this catted pipes to anyone looking for a rough sound on a bearable level.

    Big difference over the stock H-pipe.

    I had a shop install this x-pipe, they charged me for 1 hour of labor. This pipe fits great with no issues. I am running the Pypes Pype bomb axle-back and could not believe how much louder and more aggressive my exhaust got! I get compliments and questions about my exhaust at least weekly. It is a very loud set up, I am going to be welding in some Pypes M-80 mufflers to tone down the volume a bit. I have been running this pipe for 6 months now without any issues at all. Overall I highly recommend this product to someone in the market for an x-pipe. If loud is what your after, the Pypes Pype bombs and BBK catted x-pipe should do the trick.

    Just what the Dr Ordered.

    Mission accomplished. It's aggressive sounding, when pushed it sounds like a NASCAR, I can creep through town without attracting much attention, overall it sounds great. I run this with an Airaid CAI, Ford Racing axle backs plus a Bama tune on 93. It makes you smile a lot.

    Great pipe

    It ships in 3 parts, the two cats and the X. Removing the 02 sensors was probably the hardest part of the installation. Everything fit right, but my car doesnt have rubber mounts for the hangers on the pipe, not sure about other vehicles though.... as for the X pipe. The sound is incredible. Its a bit raspy but it screams. Definitely better flow than stock.

    Sounds great, terrible fit

    Install took approx 2 and a half hours on a lift by myself as a novice level enthusiast. getting the upper O2 sensor off was a pita. The driver side catalytic converter is rubbing up against the wall of the chassis BAD. there are to hangers on the x pipe but no where to hang them. Car sounds great when you dont hear the cat hitting the car. I'm gonna have to take it to a welder or figure out a way of stopping it. Due to fitment issues I am giving this x-pipe 3 stars. Sound wise, my car screams with the pypes pype bomb axle backs. Almost too loud and I love loud.

    It sounds much more raspy and loud!

    This exhaust only took me about 30 mins to install tops, using my friends impact gun and lift it was a breeze! Try to use some bolt/nut loosener before and after taking the nuts off just in case you might want to change to something else, even though i do no think that will be the issue at all. The loudness went up dramatically in the sense of "loud" but since i also bought the 60 series American Thunder axle back a while ago from AM as well it still has that "Now thats a Mustang!" sound everyone loves to hear going down the street! It fit perfectly, BBK also includes hanger units on the product as well, but my stock 2010 GT was not equipped with the rubber holsters so i did not use them, but i recommend getting at least one O2 sensor extender for the passenger side sensor though. Like i said it sounds AWESOME and is definitely worth every penny and i feel it a lot in high end as well! Should feel it even more after my CAI intake and SCT tuner install.

    Got my x pipe quickly from american muscle. SHES ALIVE!! Sounds great when you get on it and i felt a slight high end power increase! Driving normally sound is not so loud almost like stock. When you get on it she sounds mean! Install took around 2 hours with a lift taking our time.. Couldve been done in an hour if we wanted to. Install was really simple. Great Product overall! Wish it wasnt so expensive for cats but gotta pass emisions :(

    Well designed and quality construction

    I'm very impressed with BBK's quality, construction, and fit/finish. The product arrived in the BBK cardboard container, there was minor damage to the clamp and x-pipe tubing, solved with a ball peen hammer and 2x4. Installation was straightforward. You do need an ample amout of clearance under the vehicle. I would also suggest a jack stand or floor jack (if you install by yourself like I did) or have an extra set of hands. There is a Ford TSB 08-23-04 that addresses the transmission crossmember exhaust isolator delete and proper exhaust clearance. My 09 had this TSB applied already. I was confused where the exhaust hangers on the x-pipe. Install took about three hours from start to finish. I do like the fact that BBK uses factory style pipe clamps. Post installation: I highly recommend either open your garage door or back it outside when you first start up the car. The cats and the x-pipe produce a good bit of smoke for a while. All in all I'm very happy with the new sound and increased performance. My sons 06 GT is next.

    Good low note

    We had to switch from the off road x pipe to the x pipe with cats to get rid of the check engine light on a 2010 GT. Definitely not as loud as the off road version, but has a nice deep throaty sound and definitely not as raspy. Install wasn't much different than the off road except the top nut on the passenger side is a little more difficult to get to, but NEARLY as bad as with the stock exhaust.

    This product is excellent

    I recently bought this product (bbk x-pipes) for my 2007 Mustang GT. I had it installed and it really brought the sound of the cams out and provides greater performance. My Mustang club wanted to know where I purchased the pipes and of course American Muscle where I purchase all my parts needed for my Mustang and will continue to do so. Shipping was quick, ordering time is fast, and this will be the only site I order my products for my muscle car!
