ARH Ford 2011+ Mustang 5.0L Full Length Headers with X-Pipe


American Racing Headers' 2011+ Ford Mustang GT 5.0L Full Length Headers with X-Pipe

Ford claims 412 HP. We say it’s considerably more! The new 5.0L Coyote Mustang is here and quicker than you can blink, ARH has a header system. 100% U.S. made using the finest 304 S/S, the system fits great, installs relatively easy and produces HP gains normally seen in much bigger V8’s.

Through stock mufflers and mid pipes (and no tuning) power was up 32 RWHP. We were blown away and you will be too!

Additional features include: 3/8” thick flanges, merge collectors with scavenger spikes, a direct fit X-pipe, your choice of no cats or 200 cell metallic substrate cats, and your choice of 1-3/4” or 1-7/8” primaries.

   

Vorshlag ran the 1 7/8" primary headers with the catted X-pipe on our 2011 Mustang GT 5.0 (click here for Project Build Thread) and we highly recommend this primary sized header to our customers. We have not experienced any loss of low end power with this "larger primary" tube size and our own dyno graph showed gains throughout the power band. Custom dyno tuning helps you gain even more power with these motors, especially if you have an aftermarket intake as well.
