Description
Increases Overall Performance. Add even more horsepower and torque to the rear wheels by eliminating those power robbing catalytic converters with a BBK Off-road X pipe. A BBK X pipe will greatly improve your pony's exhaust flow to increase overall performance and sound.

Race Car Growl. A free flowing BBK x-pipe 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. This BBK direct replacement X-pipe features 2.5” diameter CNC mandrel bent aluminized tubing and a merged X crossover to improve exhaust flow. Additional features include factory O2 sensor locations, and OEM style die-stamped flanges all to ensure a perfect fit.

Application. Specifically designed to fit the 1999 to 2004 4.6L Mustangs, including the GT, Bullitt, Mach 1 and SVT Cobra. This Off-Road X-pipe is a direct fit replacement for the stock mid pipe.

Technical Note. This BBK product is not legal for use in emission restrictive states.

Looking pair this O/R X Pipe with a bama tuner, CAI, and flowmaster catbacks, do I still need the 02 extension and MIL eliminators?

Would it be an easy swap from the BBK catted X-pipe? I have the BBK catted x-pipe on my 03 mach 1. Would swapping the two be fairly easy? Do the fit any different?

  • It should be a fairly easy switch as they both fit in the same location, only difference is that this off-road version doesn't have the cats. Hope this helps!

    Great

    Really easy to install. BBK always makes great products. It really opens up the car with my bbk cai, 78mm tb, roush side exit pipes and a bama custom tube. This is what mustang should sound like. Had to get new o2 sensours for the frount, the rear ones are turned off with the tune so no need for mil eliminators.

    Raspy and Angry

    Gives the Mach a very raspy and angry sound, true race car sound. A little to much rattle and tin can sounding for my taste.

    Good for the money

    Installation of this product is easy, the removal of the stock mid-pipe is what can be tricky. I was unable to get enough torque and leverage on the ratchet with the swiveling ratchet on the passenger side using the method as shown in the instructions, so i dropped the starter in order to get better angle, leverage, etc. After that, istallation was easy, bolted right up and fit well with my aftermarket SLP exhaust, also much easier to tighten and loosen the bolts at the manifolds on the new mid-pipe as their are now no cats or pre-cats to work around. For 2004 GT models you will need 02 extensions as well as the MIL eliminators if you don't want to trigger any codes. Noticable changes in sound, moderate gains in performance.

    This hot tin roof has NO cats....

    If you MUST have catted x-pipes by law then what choice do you have?! IF you can go with uncatted x-pipes, then the BBK Off road x-pipe will deliver E V E R Y T H I N G American Muscles says it will. I can actually use 1st gear to pull smoothly away from a complete stop OR light up the NITTO's and bang my short shifter into 2nd & 3rd to hear the birds cherp (just better not miss the shift to 4th at 85 to enjoy the Flowmaster resonator music). No issue with stock 02 sensors and harness, perfect fit with BBK shorty headers and AM Thunder Exhaust. Nice exhaust note will put you to sleep on the interstate at 2K RPM OR open up that Accufab TB to 3~5K and get the H.E.A.T.'s attention. A diablo tune will put your fuel mix, aft 02 sensors and octane all in line, add the typhoon manifold and cams and we will see you on 'Pass Time'...... CAUSTION: DO NOT REV YOUR MUSTANG WITH THESE OFF ROAD X's because car alarms will go off.

    outstanding

    i ordered this X-PIPE system because i read nothing good about the pypes brand X-PIPE system and did not want to gamble with my money but i am a happy customer i got my X-PIPE in 3days after ordering it and got it on that same afternoon i took it to an exhaust shop the mechanic said it fit fine everything lined up it only took him about a hour. this system sounds great it is loud i love it its definitely a head turner if you order this you will not be disappointed. the only reason i gave it four stars instead of 5 was the cross over section of the system had a little blemish of it but that is no problem to me just being honest but i still love it great work BBK and AM.com
