    Features & Details

    • Increases Horsepower and Torque
    • Race Car Growl
    • For Use with SLP Long Tube Headers

    • 2.5" Mandrel-Bent Stainless Steel Tubing

    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.

        Do these bolt on with Mac LongTube Headers.

        • These will bolt on with the Mac long tubes however the fitment may not be the best. It is recommended to match up the same brand mid-pipe with the header when doing long tubes.

            Return product back.

            This product arrived very quickly, but it didn't connect to my 1996 Gt factory. So I had to return this product. I'm still curious what product I should use to connect to my factory pipes without obtaining any check engine light.

            Check Engine Light Finally Gone!

            Along with the Ceramic Longtube Headers from SLP they literally create an exhaust symphony! Although it is Catted, for those that love a LOUD deep sound believe me when I say it's still there! Easy install, great sound, and performance gain, an absolute must have!

            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!

            SLP all the way

            this x-pipe combined with the SLP long tube headers and LM1 system has to be the best sound i have heard from any mustang. has a deep growl to it and definatley a head turner when you get on it. Thanks American muscle for the great service and fast shipping. BEST in the business!!
