Increases Overall Performance. Add even more horsepower and torque to the rear wheels of your 3.7L V6 Pony by replacing those restrictive factory cats with a brand new BBK Catted X-Pipe that features high-flow catalytic converters. A BBK catted X-Pipe will significantly improve your pony's exhaust flow to increase overall performance.

Race Car Growl. This free flowing BBK x-pipe for the 3.7L V6 Mustangs 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 Construction. BBK's X-Pipes use a free-flowing 2-1/2" diameter CNC mandrel bent aluminized steel tubing and a merged X crossover to improve flow. This X-Pipe features High flow catalytic converters to provide a significant horsepower increase over the restrictive stock cats.

Application. This BBK Performance Catted X-Pipe is designed to be a direct bolt-on for the 2011-2014 3.7L V6 Mustangs with either aftermarket short tube headers or the factory manifolds installed.

Please Note. Stock 2011 V6 Mustangs come stock with a Mid Pipe that resembles both the H-Pipe and X-Pipe designs. This hybrid Mid Pipe was created by Ford to help add additional power and sound to the V6 straight out of the factory. This BBK aftermarket X-Pipe will further help you reach maximum air-flow equaling additional power.

What are the hoursepower and tourque gains?


  • Thauser Changing from a stock set up to this BBk Catted X-Pipe will always add a little HP and Torque to your 2011-2014 V6. It's hard to say how much. Other than to say the engine will breath much better. With the right CAI system, aftermarket exhaust and a tune. A good 5% +/- increase. Duke7

Before placing an order, just wanted to make sure that these would fit with BBK Ceramic Tuned Length Shorty Headers Item#56235 and Magnaflow Street Catback Exhaust Item#48043 which is currently installed on my '14 V6.


  • Yes, this BBK mid pipe system will fit up with all of the current components on the car and the bbk ceramic tuned shorty headers.

Will this pass emissions testing? I'm not subject to CARB regs here in NY, but still concerned about being able to pass. (Plan to pair with BBK shortys; Roush CAI and A/B already installed.) Thanks.


  • The BBK Catted X-Pipe will past emissions in most states requiring an OBD II Emissions test, however due to a large variance in emissions testing standards from state to state, it is best to check with a local emissions inspection station to ensure these would meet their regulations.

Is this X pipe legal in California? I know the shorty headers are and was hoping this would be too.


  • This X-pipe unfortunately is not California legal.

I have a Roush CAI, BBK throttle Body, BBK Shorty Headers, and a Roush Axle Back Exhaust. My question is will this make my car too loud for a daily driver. I love a good sounding exhaust but I also don't want to be "That Guy" who wakes everyone in the neighborhood up.


  • It would be difficult to say exactly how loud this would make your vehicle as sound is subjective. We would highly recommend listening to a few sound clips with a similar set-up to see if the addition of this part with your set up would be too loud for your liking.

    V6 BBK Catted X-Pipe

    Bought the BBK catted x-pipe back in December, but I was unable to install as I could not get to one of the flange bolts that connect to the manifold using only jack stands. So, two weeks ago I was finally able to get my car to my local ford dealer who installed it for $150. Prior to installation my stang was already running an Airaid CAI, Borla Attack axle back exhaust, BBK 73mm throttle body, and Bama tune. After the dealer installed they called to let me know they were done and my advisor told me that the technician said I might want to go back to the stock h-pipe because adding these made the vehicle extremely loud. I was skeptical as I only have a V6, but after showing up to the dealership and starting the vehicle the technician was correct my car was loud. Even my advisor was shocked by how loud it was. The technician at the dealership said it was an easy install and fit nicely. As for added power I have not noticed any power gains with the catted x-pipes installed. Again, the sound is the big difference and is somewhat loud when going through the gears (1st to 4th), but once 5th and 6th gears are reached the sound mellows out. No drone and would be easy to drive on a trip. I am still debating on whether to return to stock h-pipe. Guess I will wait to see if my neighbors complain about the noise.

    The installation took about an hour an a half. Bbk doesn't send you new bolts so you have to re use the ones on your stock h pipe. The left pipe was fine the right one I had to wd40 it. But when its all put together mannn this thing is LOUD. Trust me I was scared to get this since NO ONE has reviewed it but It was worth the risk. I'm running C&L intake Borla ATAK axleback and Bbk 73mm throttle body. Be prepared to smell smoke for about 3 days! BUY THIS NOW!

    Loud and nice sounding

    If your looking for a nice exhaust setup with some real loud exhaust note this will definitely help you achieve that. Installation was easy bolts right in you will need a lift or some jack stands because the stock exhaust is pretty heavy. This makes your stang scream when you push the throttle. Definitely happy with this choice.

    Major performance upgrade as well as big sound

    I've seen a lot of the reviews talking about the sound so I won't go into too much detail just know that these will make your car INSANELY loud with any setup you have. My mods are Roush axel backs, Kandn cold air intake, 93 race tune by mpt and now the x pipe. I HIGHLY recommend that you go ahead and get a set of 18 inch glass packs to use as resonators with this purchase. I used magnaflows and the car sounds so much better now. As for performance I have not had the car dynoed so I don't have any numbers. But I do have before and after results from racing my buddies. This x pipe is what you need in order to run with the V8s out there. In these races the only difference was the x pipe. All races were from 20-120 on a private closed road. 1st gen Cadillac CTS-V walked me badly just constantly pulled on me and by 120 had me by about 5 car lengths. Now we're pretty much dead even. 2000 camaro Z28 beat me by 2 car lengths and pulled on me after 1st gear, now I beat him by at least 2 car lengths and am ahead the entire time 2000 trans am ws6 don't even want to talk about it. Now I'm only 1 car length behind I can also keep with a 2012 camaro SS. As you can see the x pipe adds just as much performance as it does sound and I highly recommend it. It really amps up the V6 top end which is where it will lose to most V8s. 3V mustangs can't even touch me anymore. And this is all on stock 273 gears as well. Love the x pipe.

    Awesome part!

    Install was fairly easy just get ready to use extensions on your ratchets or impact gun, other than that makes your car definitely a lot louder and gives it a real v8 sound on everything. Start ups, revs etc. definitely recommend this to anyone who wants they're car loud I'm running these with shortty bbk headers and pypes axel back sounds amazing. Little rasp but it's manageable

    Need to buy ASPA

    These x-pipes are loud you can heard me like a block away. They are a great mod if you want a loud rumble to your car the install was pretty straight forward it took like 1/2 hour to install them. Also when removing the bolts that connect the x- pipe and headers be very careful not to damage them but they might be rusty.

    This BBK X pipe is what my mustang was missing. My MBRP street cat back gave the car a deeper note but it wasn't loud enough. The BBK X pipe made a HUGE difference. This combo has little to no drone. Next I will purchase the BBK headers.

    Sounds great

    Love the exhaust, idle-3k sounds so mean and aggressive, 3-5.5k just plain loud and raspy, 5.5k-7k sounds normal. Got this xpipe put on after having roush cai, bbk 73mm tb, bbk shorties, aluminum ds, bama 93tune, and borla atak axleback. Sounds great, wish I would have gotten it sooner, price was the only thing holding me back. Thanks AM!

    Bbk catted x pipe

    I got the bbk shorty tuned length headers, as well as the x pipe along with the magnaflow street catback. Installation altogether took about 4 hours the x pipe took maybe 30 mins if that. I can't speak for just replacing the x pipe. But it makes a great exhaust flow. And great air flow.

    Great Sound, Tough Install

    Background and general satisfaction: I purchased this X-Pipe mainly because I wanted to make my Mustang louder. These pipes are loud. I am using the Borla S-type axle-back which have a good sound on their own, but the BBK x-pipe amplifies that sound to the max. 3000 RPM lets out the most loud, obnoxious, disgusting, raspy tone ever. People driving behind me have switched lanes because of it. I love it. Fit: The pipes fit, there's no doubt about that. I did notice that after installation my mufflers shifted inward a bit and now do not sit centered in the rear valence. I'm okay with this, and it can possibly be fixed through some adjustments. Installation: Somewhat difficult without a lift and the proper tools. I used a jack in my driveway with a friend's help. Removal and installation of the catalytic converters required a ridiculous amount of wrench extensions in every which way. My '13 has a lot of miles on it, and the bolts were heat-worn and rusted, and needed a lot of strength. We ended up stripping out the exhaust manifold flange bolt and I had to go to my local Ford dealer to buy a new one for $12. This did the trick. I drove the new pipe for 2-3 weeks and begun to hear an exhaust leak, almost as if there was a baseball card in a bicycle wheel. Tick tick tick tick and it was related to RPM. Decided to bring it to my local mechanic. The driver's side catalytic converter came loose and needed to be tightened. I attribute this to the difficulty reaching those bolts and would recommend this install be done by someone with the appropriate power tools, or a mechanic. Conclusion: I love this pipe. Any problems I had with it are all attributed to mistakes made by me during the installation. That being said, the installation isn't easy based on the difficulty getting to those exhaust manifold flange bolts. I wouldn't go back to the stock pipe if you paid me, though.

    Race Car Growl? NO. more like Rice Car Growl!

    I was really excited to install this specific x-pipe after researching, reading reviews, and looking through videos for an appropriate sound/performance I needed to make my V6 sound more aggressive. Got it installed at the shop for $100. When I first started the car, I was stoked! Sounded loud and aggressive. BUT when I hit the street and hit the gas, I was so embarrassed!! After 2500~3000rpm, the car screams (as other reviewers noted), but it screams like an overdone Honda Civic. I thought it was because of the stock exhaust. About a month later I installed GT500 quad exhaust. Again sounds great in low rpms, but when it hits 3000rpm, boy I just want to yank it off before anyone could hear it!! If it didn't cost so much to uninstall it and return it, I would have done it in a heartbeat. If you like that #raspy#Honda#Civic#ricer#lowrider#highpitch sound, then this is for you.

    I was going to attempt myself but decided to have pepboys do it. Took them about 2 hours. Install instructions are vague. Make sure you have extensions for sockets if you are going to do it. Jackstands dont give enough room. Tried that and decided to let pepboys do it. These pipes sound awesome. Its a V6 for sure but sounds as close to a V8 as it gets. No drone at all. Just a terrific sound. I used dynomax after market axleback mufflers. Couldnt be happier. AM was quick on shipping. Very pleased.

    Very LOUD

    I was hesitant to buy this because of the mixed reviews. As always American muscle took good care of me. The X-Pipe has made my car sound very mean at idle and between 1k-4k RPMS. I've noticed when you pass 4k the rasp esnues.. I was actually able to feel a difference performance wise, it just feels like it flows really good. You need to have a very specific setup for this X-Pipe.. I have Borla S-types and BBK short headers.. I can imagine if you had a really loud exhaust plus this mid pipe it can be pretty loud.. I still recommend this X-Pipe but know that it does make your car loud lol.. I love it though it's music to my ears.

    Nice tone and sound

    These pipes sound good. Sounds way better from the outside then the inside of the car though. I'm running the catted xpipes, the flowmaster force 2's, 73 throttle, Airaid intake, and bama tune, oh actually I'm back to stock with the tune I can't figure out how to get the drivers installed on any of my computers whatsoever, BAMA is good but directed me to SCT customer service which is non existent. It sounds good but I'm just not feeling how it sounds from the inside of the car. I was going to put my stock pipes back on but when I got a friend to press that gas throughout the entire RPM ban while I stand back I figured I'd keep them on cause it sounds really nice outside the car. I don't know if it's because I'm coming from a v8 with the full exhaust or not but from the inside after 2.5 RPMS it be just too high pitched. The idle sound is nice though. Hopefully my next mod(headers) will deepen the sound at higher RPMS. The drone, I really don't mind the drone I'm actually quite use to it with my v8 and love it... I can still hear my phone calls so it doesn't bother me. Over all these pipes are nice and it really does make a difference and you'll see.
