More Power and Torque. The SLP Shorty X-Pipe uses free-flowing mandrel-bent tubing with a genuine X style crossover and high-flow catalytic converters to provide a significant increase in horsepower and torque over the restrictive factory catted pipes when installed in conjunction with SLP's Long Tube Headers.

Race Car Growl. This free flowing SLP x-pipe for the 1996 to 2004 Mustang's not only increases power, but it also adds a raspy, race car growl to the sound of your exhaust with its modern "X" crossover pipe design.

Quality Stainless Steel Construction. Constructed entirely from 2.5" mandrel bent stainless steel tubing for improved exhaust flow, this SLP mid-pipe features a true "X" crossover, not a poor-flowing clam shell imitation that other companies use. The included SLP High flow cats far out perform the restrictive factory catalytic converters to increase rear wheel horsepower and torque.

Application. This SLP Shorty catted X-Pipe is designed to fit the 1996-2004 GT, 2001 Bullitt, 2003-2004 Mach 1 and the 1996-2004 SVT Cobra Mustangs with SLP Long-Tube Headers installed.

Technical Note: This SLP product may not be legal for use in emission restrictive states. Check local ordinances.

will the x pipe work with bbk ceramic long tube headers??? i want to buy bbk ceramic longtube header and this x pipe so i want to make sure they will bolt right up to each other???

  • The rule of thumb for installing Long Tube Headers is to stick with the same brand for both the headers and the shorty mid-pipe. This ensures proper fitment as they were meant to be installed together. We've found this rule to be especially true of the SLP brand. That being said, you may be able to install this with BBK LTH, but be mindful that some modification may be needed to get everything bolted correctly. I'd suggest getting the BBK Shorty Mid-pipe if you want the BBK LTH. Hope this helps to answer your question!

    Great sound

    Sounds great. Bought this with the SLP Long tubes and Magnaflow cat back. Nice mellow sound until you hit the go pedal and then it roars.

    great product from slp like always, the only down fall is that the cats hang a little low so if you lower your car two inches or more it will hit over speed bumps and good size bumps in the road, but it is great mad a big difference in the sound and tone a bit deeper tone too it.

    Don't Buy

    Ths is the first "true" x-pipe I've used. Ran a Bassani clamshell that sounded much better and worked well. This x-pipe sounds like a herniated bumble bee. Lost power versus the factory four cat deal. Using magnaflow mufflers, before and after. The 2.5" tubes lose a third of their diameter to form the X. Giving up .8" x 2 tubes = 1.6". This doesn't even calculate area lost. H-PIPE!!!! Might work on a SOHC but not a DOHC!
