    Increases Overall Performance. Add even more horsepower and torque to the rear wheels of your 3.7L V6 Pony by eliminating those power robbing catalytic converters with a BBK Off-road shorty X-Pipe. A BBK X-Pipe will greatly improve your pony's exhaust flow to increase overall performance. This BBK x-pipe is specifically designed to be used with BBK's 1642 Series full length headers.

    Race Car Growl. This free flowing BBK x-pipe for the 2011-2014 V6 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. It also features OEM style hangers that attach in the stock locations for a perfect fit.

    This BBK Shorty Off-road X-Pipe is specifically designed to fit the 2011-2014 and newer 3.7L V6 Mustangs with BBK Long-Tube Headers installed. Intended for off-road use, does not include catalytic converters.

    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 aftermarket X-Pipe will further help you reach maximum air-flow equaling additional power.

    Technical Note: This BBK product is intended for off road use, and is not legal for use in emission restrictive states.

      Worked great but......

      The photos on the website misrepresented the actual product. When we called and asked about the kit, we were told that the photos were accurate. The reason we ordered this exact kit was because of the location of the O2 bungs in the photos. When we received the kit, the O2 bungs were in the straight pipe location and not inside the bend as pictured. We got lucky with the location of the new cats and the cat deletes we made for racing but it was tight. Had the O2 bungs been where the photos showed, the install would have been much easier. AM seriously needs to update their photos!!

      check engine light a few hours later

      So after I got my bbk lths and o/r xpipe installed. A few hours later the check engine light came on. Error codes P0420 and P0430. They keep coming on even after I retune the car to take. Not happy about this.

      Off-Road X-pipe

      This off-road x-pipe is by far the best one out there for your 3.7 v6 mustang, I can personally tell you it makes your car sound a whole lot better.

      Worth it

      This product really increased flow, and the sound is just what I wanted, the only problem I had was during the install. The pipes didn’t match up to the ends of the headers, I had to attach one side then have a friend Pry the other side to attach the other side.It didn’t take too much effort, but would have been very difficult without a lift

      Great mod, but watch out for cops

      I installed it over a week because it was too cold to stay outside and work on it for over an hour at a time, but sounds awesome. Only issue I've had was my neighbors all complaining about how loud my exhaust is and getting pulled over for it. Haven't gotten a ticket but I'm expecting one soon

    do i need catalytic converters for this? i have a 2012 v6 mustang

    • This part replaces the catalytic converters. It will not allow you to pass emissions testing if it is required in your area. Ithis is why it is classified as an "off road" only part.

    Will this x-pipe work for my 2016 v6 mustang along with Long Tube Headers?

    • Unfortunately this will not, the 2015 and up Mustangs will have a completely different exhaust setup. The only part that will be compatible is the long tube headers by themselves.

    After installing long tube headers and off-road x pipe will I need a tune?

    I have a 2014 mustang gt will this work for my GT model?

    Will this fit with another brand of long tubes such as flowtech for example or is it just with bbk ??

    • This mid pipe would be a perfect fit with the BBK long tube headers. You can use this mid pipe with a different brand, however, modification may be required due to the fitment with different brands not being the same.
