Product Description

American Racing Longtube Header Kit
Increase horsepower and torque in your 2012-2014 Mustang Boss 302 with a high quality set of longtubes from American Racing Headers! ARH set the standard for quality in the exhaust world with their top notch products. This longtube header kit features 1 3/4" primaries to provide maximum flow over the factory manifolds. The headers flow into an off road x-pipe to replace the restrictive catalytic converters and provide an intimidating sound. The fit and finish of these American Racing Headers is second to none! This kit includes the correct Boss 302 side exhaust hook ups for a direct replacement to your stock cat back.

ARH Quality
American Racing Headers proudly makes all of their products in the USA. This 2012-2014 Mustang Boss 302 header and mid-pipe kit is constructed entirely with U.S. made 304 stainless steel tubing. These headers start off with 3/8" thick flanges with tig-welded and hand ported inlets. The 1 3/4" primary tubes are all one piece design for 100% leak-free performance. These primary tubes flow into the included 3" off-road X-pipe. This combination will maximize flow, horsepower, and torque!

Emissions Note
This longtube header and x-pipe kit includes an off-road x-pipe. This x-pipe is intended for off-road use only and is not street legal.

Installation Note
ARH recommends reusing factory gaskets or replacing with Ford OEM set.
