Description
More Power and Torque. The SLP 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.

Race Car Growl. This free flowing SLP x-pipe for the 2005 to 2009 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.

Upgradable Modular Design. SLP's exclusive three-piece modular design makes it possible to easily upgrade to SLP's Long-Tube Headers without the need of purchasing a brand new X-Pipe by just removing the down pipes. This unique modular design also makes it easy to install this X-Pipe on your Mustang with just basic hand tools.

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 Catted X-Pipe from SLP is designed as a direct bolt-on for the 2005-2009 GT and 2008-2009 Bullitt Mustangs with either aftermarket short tube headers or the factory manifolds and a dual catback exhaust installed.

Will slp x-pipe work with other brand long tube headers?

khankerson528

  • It's better to stick to the same brand and not try to mix and match. This ensures proper fitment as they were meant to be installed together. I wouldn't suggest mixing brands.

    Good but....

    Had a muffler shop do the install which was no issue. Bolted right up to the Pypes catback.. The reason for the low rating on fitment is this: These pipe hang looow.. My Mustang is stock height and I am having issues with bumps and ramp when driving day to day. I love the muscle car look which is why my car is stock height. I only plan to get new shocks, sways and control arms. I can only imagine most who love to lower their Mustangs and have these pipes installed driving day to day. So please be warned.. Other than that, fit and finish is fine, The sound is lovely and performance combined with the exhaust intake and Bama is the power I have been looking for.

    SLP catted x-pipe

    I recently was looking at some different x-pipes for my 08 stang and came across the slp, bassani and magnaflow. I had flow master in mind to but it doesn't sound all that nice. Just not the right notes. So instead I did some research on the potential gains and rumbles of these exhaust and it brought me too two choices MF or SLP. After calling American muscle first hand, George was very helpful with pointing out the cons and pros of these exhaust and places that might be of help with the fine tuning of installing it. It was such a help to know that these people actually care. I eventually went with the more cost friendly exhaust (slp) and it came out beautiful. You get that loud raspy pitch from the middle of the car and then axle back i have a magnaflow exhaust which gives it a deeper rumble. The best part is you can actually feel the gains come from the less restrictive pipes! I used bama tunes as well to help with the tuning! (SF3/X3 tuner) Well worth the money as well.

    SLP Exhaust System

    Guy's I hope to here some response to this. I bought the SLP cats, x-pipe and loud moouth rear pipes(no mufflers). I took my 2008 GT Mustang to a speed shop for Dyno and my check engine light stays on now. I was informed by the speed shop that SLP's are notorious for this problem as the cats are to sensitive. they suggested a $1200. pro street computer that would tweak and resolve the problem. I called A M and they said for me to send my Diablo info and car computer info and they would write me a temporary chip to turn off the O2 sensor. But I will be a problem come Smog time next year. I called SLP and they informed to take my car to a muffler shop and have them check the left exhaust pipe that comnnects to the header maifold as they suspect exhaust leaks. My Diablo alarms indicate to rich bank 1 to rich bank 2 and ODB alarm. Please help me in which direction to pursue. Since the SLP is a clamp on modular systen I personaly would suspect exhaust leaks. You or anyone else experiencing this problem may respond to realjack@earthlink.net

    Awesome Product!!!

    Just installed on Saturday to pair with my Flowmaster American Thunder CBE and WOW! Sounds incredible! This paired with 4:10 gears, CAI, and BAMA Race tune = Holy GOD! Install was a breeze on the lift. Hardware worked as anticipated. I was stoked that I didn't see a Check Engine Light when I started it for the first time.

    SLP catted x pipe

    This x pipe went on not too easy but easy enough, i have it on my 08 gt with borla stingers and it sounds amazing! I get a lot of compliments on my cars sound and the catted x pipe was one of my favorite additions to my car! The only problem is my car is lowered so the cats scrape on most bumps so i gotta go at an angle to avoid damage, but definitely worth it!
