    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.

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

    ColbyP

    will the x-pipe section align to my factory cat pipes? looking to cut oem pipes to preserve cats for now and clamp to the new x-pipe.

    jasone

    My 02 GT already has ground clearance issues because it is lowered. Will this x-pipe create more issues due to clearance? Or will this be better with ground clearance over the stock H pipe?

    TammyS

    • When properly installed, the BBK Off-Road X-Pipe will sit slightly lower than stock, by approximately 1/4"-1/2".

    Would I be able to weld my catalytic converters onto this x pipe to make it smog legal?

    Chris

    • You would be unable to weld the OEM cats to the BBK Off-Road X-Pipe. This would constitute modifying the emissions equipment causing a failure for smog testing.

      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.

      Noise

      I have a supercharged 4.6 2v mustang saleen borla exhaust. It sounded pretty good with the cat system on it, but with the off road the noise it devastating.

      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.

      Good raspy tone

      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.

      Great sound

      Loved the growl it gave my 2001 GT. Really woke the car up from the factory H-pipe. Turns more heads than it ever has now. Also, doesn't add too much drone while just cruising but sounds amazing when you get on it. Had to hammer the cone of the left side pipe meeting the manifold though to get rid of a slight leak.

      Loudest one on the road

      I went to 3 different car meets, not one person was louder than me. I’m running this x pipe and custom fabricated straight pipes and my car just roars. every time I get the car on the road someone is trying to race me. You could definitely feel a decent power increase so this x pipe is definitely worth the money.
