Features & Details

  • Increases Horsepower and Torque
  • Race Car Growl

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 stock catted pipes when installed in conjunction with SLP's Long Tube Headers.

Race Car Growl. This free flowing SLP x-pipe for the 2005 to 2009 GT'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 stock catalytic converters to increase rear wheel horsepower and torque.

Application. This SLP Shorty catted X-Pipe is specifically designed to fit the 2005-2009 GT, 2008-2009 Bullitt and 2007-2009 Shelby GT500 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.

Amazing!

This X pipe gives me a MUCH deeper sound at both idle and throttle than the stock H pipe did. It is not raspy in the least. It sounds like a demon is coming out of your tailpipes, and is nice, healthy, ...

I'm having trouble finding the SLP branded long tube headers for this x pipe. Are the long tube headers not available to puchase, or are they not available period? I haven't seen them on this website, or any other mustang specializing website, nor the SLP website. Are there any options you can recommend to work with this mid pipe?

Could I use this with pypes mid muffler true dual exhaust/ with pacesetter long tubes on a v6 mustang ?

  • Unfortunately, the SLP Catted X-Pipe is only designed for the 05-09 GT and GT500s. It is not designed for a V6. Also, this X-Pipe is meant to be bolted to the SLP Long Tube Headers. It will not work with the stock manifolds or other manufacturer headers.

My mid pipe is damaged and was looking to replace it I was looking at the slp catted x pipe. I see some people say u need long tube headers to make them fit on other brands. If I purchase this x pipe do i really need to buy long tube headers to make them fit? or can I just simply use mid pipe and replace my damaged one and still run my exhaust like that. I was really just hoping to replace my x pipe I need it to pass smog in c.a. sorry for the silly question I just want to be sure.

  • This SLP Catted X-Pipe is specifically designed to be used with long tube headers only. SLP does offer a Catted X-Pipe for stock length/short headers, Item 23022. The long tube version could be modified to fit your existing unit, however, it would require cutting, clamping and perhaps other custom alterations. http://www.americanmuscle.com/slp-x-pipe-catted-2005.html

I'm unable to find find SLP long tube headers on neither SLP or AM's Websites for a 2008 Shelby GT500. So my questions is, will these fit with JBA Long tube headers or any other brands?

BelleRougeRed

  • The SLP Catted X-Pipe (05-09 GT, GT500 w/ Long Tube Headers) features a special connection that only works with SLP Headers. Though, you can do some modifications to get other headers to work. But it will not be a direct bolt on.

    Amazing!

    This X pipe gives me a MUCH deeper sound at both idle and throttle than the stock H pipe did. It is not raspy in the least. It sounds like a demon is coming out of your tailpipes, and is nice, healthy, loud (but not obnoxious), mean, and will definitely turn heads. I am extremely happy with the quality and the sound that SLP and their exhaust products provide, and I dont ever plan on getting anything else.

    Excellent!

    S197 stock was so restrictive with power/noise when it came to exhaust, and I\'ll tell ya that this X-pipe and high flow cats really opened both up, coupled with the SLP Longtube Headers! SLP is the only way to go here.

    Awesome sound

    I installed the SLP Catted Shorty X-pipe in a few hours with the help of a car lift. Without it these would be pretty hard to put on yourself. Fitment was great. I love the sound these make when combined with the SLP Loudmouth axle-back exhaust; great muscle car sound but not overpowering because of the cats. I'm definitely happy with these x-pipes.
