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 Year: 2002 Model: GT

  • 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.

  • This off-road x-pipe would be a great complement to the BBK Shorty Headers! This mid-pipe will bolt up with no issues!

Will this fit slp long tube headers if i got a automatic transmission?

StangWang78 Year: 2001 Model: GT

  • This x-pipe will only bolt up to stock manifolds or shorty headers. To install Long Tube headers, they would require the use of a shorty style mid-pipe to compensate for the longer length of the headers.

    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.

    Extremely Loud

    I love the way this X-Pipe sounds. I have it mated with a set of flowmaster original 40 series mufflers and I must say "It is LOUD". but it has a really nice tone to it. Definitely turns heads and recieves plenty of compliments. The only problem I had installing it was where it bolted up to the the left side manifold. I had to extract the original manifold studs and replace them with bolts. Also had to oblong the holes on that the left side flange because the holes where spaced to far apart. Other than that little side track, it fits perfectly, tucks up nice and tight gaining more ground clearance for them pesky speed bumps. I recommend this x-pipe if you want your car to be loud.
