    Will I get a CEL? By putting this o/r x-pipe on will I get any CEL's because with this I'll have no cats. Thank you

    • Yes you will, if you buy some plug in mil eliminators it will fix your problem or if you have a tuner you can shut the codes off

    can this be used as shorty x-pipe later on ? my current exhaust setup is stock headers and stock h-pipe paired with flowmasters. I've been thinking about getting this x-pipe for a long time but my only concern is that at some point later on, i will be getting bbk long tubes (money willing) and I'm not sure if i can then just simply remove the 2 extension arms that connect the X figure in the pipe to the factory headers and re-use the x-pipe (which would technically be bbk's shorty x-pipe) with my long tube headers ? I looked at both bbk's shorty and normal x-pipes and the only difference i could find was the 2 extension pipes (how ever i could be wrong).

    • Unfortunately not. The tubing lengths on this off-road mid-pipe are not the same as the shorty mid-pipe and therefore, they can not be interchanged. If you switch from stock headers to the long tubes later on, you will need to purchase the shorty mid-pipe at the same time for proper fitment.

    I have already slp on my car and i want to install the off road x pipe is it legal in AZ?

    • Unfortunately, we are unaware as to if this would be legal in Arizona and would suggest reaching out directly as to where you have your emissions tested in order to best verify.

    Will this work with the bbk shorty headers that I currently have installed? Iā€™m running bbk shorty headers, stock H pipe and magnaflow after the H pipe

    • Yes, this x-pipe will work with aftermarket shorty headers or with the factory manifolds.

    If i have a side exit exhaust, would i have to run my pipes through the back if i buy this?

    • No, this x-pipe wouldn't affect a side exit cat-back if you have one installed on your Mustang.

      Best first upgrade

      This and a cold air intake are the first two first upgrades you can do to your new edge, It completely changes the sound and overall experience of the car even with a stock axle back. Only thing to note is you may need oxygen sensor harness extensions for the front O2ā€™s.

      Bbk offroad xpipe

      When I received the x-pipe in the mail i was excited to the box sitting there with a glowing light around it. I installed it the next morning before work. The first startup sounded amazing! I drove it through the neighborhood to make sure everyone could here me. Sounds like a real race car now! I blew down the highway with a hugh smile on my face! I love my bbk offroad xpipe.

      Great sound

      Pretty good quality, pretty difficult to install only due to the fact i only had jack stands. Would definitely recommend a lift otherwise it hangs too low. Good product though.

      2004 SVt Mustang Cobra

      I hope this review helps someone who has a 04 SVT Cobra because 04 is different from 03 SVT as the 04 SVT O2 sensor holes on the BBK XPipe are not located in the same spots as the as the stock Hpipe, the rear 02 sensors on the BBK are located in the rear which are further back than the stock location which means you need to purchase (2) 02 sensor extensions (24") and be sure to pick up a flange gasket passenger side only for the BBK xpipe, also I called American Muscle and of course they were very accommodating and polite on the phone, they couldn't tell me if I needed the parts I mentioned, so through experience I learned this and I'm passing it on, hope this helps. Oh! It really sounds awesome!!!

      BBK O/R x-pipe

      Product is great. All the necessary hardware (minus gasket) was included. Shipping was fast, and install was pretty straightforward. I have welded in Original 40 Flowmasters paired with the X-pipe. It was very loud and raspy, but after driving 1000 miles, the X-pipe has broken in, and sounds much deeper now.

      This x-pipe sounds so mean. I went from borla stingers with a prochamber to stingers with this x-pipe and this new set up is so much more aggressive. I get a lot more looks and compliments. Great bang for your buck.

      If you are looking for volume I can attest that this is what you want. My entire neighborhood hears me when I turn on my car and I love it! People pull up beside me all the time and ask me to rev up the engine and give me thumbs up.

      Fantastic!

      My 03 Mustang GT with soft-spoken so I first purchase from American Muscle the Flowmaster cat back kit. I gave it a bit of a growl but still was not aggressive enough for me. This is my first mod Motor so I didn't know what to expect with this off-road x pipe. But man this made my Mustang sound even more aggressive than I would have expected. I love this x pipe.
