    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

    going2ownastangsoon

    • 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).

    AMINGT2

    • 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.

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

    Phillip

    • 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?

    GerssonO

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

    Do you need to buy a new gasket to use this?

    CalebW

    • No you will not need any gaskets for installation of this x-pipe.

    How loud would these be on a gt with flowmaster 40s?

    ColbyP

    • With an off-road x-pipe, you would definitely notice a significant increase in the overall exhaust tone. The flowmaster 40s will have a much more aggressive sound.

      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.

      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.

      Really wakes up the cars exaust and adds a little performance. Not noticeable but it does. Very nice materials but I recommend welding it all instead of using the bolts. Will get much better results.

      I am running this x pipe with flowmaster super 40s and it sounds amazing. Gives it a very raspy tone but in a good way. Well worth the money. I would recommend having a shop install this though if you don’t have access to a lift.
