Combined with headers, an x-pipe frees up precious horsepower from your Mustang. Additionally, the x-pipe frees up some great sound. While the factory x-pipe muffles a lot of the great V8 noise, our version lets your Mustang make badass music.

Also this x-pipe is designed to be modular and fit the OEM components. What that means is you can upgrade your exhaust at your own pace. Consequently, you can change OEM components to LTH components piece by piece.

All off road performance parts are intended for off road use only and not for street use.
