Increase Power w/ GT500 Long Tube Headers

Your Shelby Mustang is already incredibly fast with its supercharged engine, but if you want to get to some insane levels of horsepower this set of Long Tube Headers and X-Pipe from American Racing (ARH) will get you there in a hurry. This high-performance exhaust package completely replaces your restrictive factory stock manifolds and mid-pipe to give your GT500 a huge increase of horsepower and torque. These ARH Long Tube Exhaust Headers and X-Pipe will give you significantly better exhaust flow and reduce back-pressure for improved performance as well as a raspy race car sound that lets everybody know you mean business. ARH pressure-tests all of their headers to ensure leak-free operation that won't let you down.

High-Quality American Racing Headers

These long tube headers from American Racing Headers feature 304 stainless steel construction, thick 3/8" flanges, 3" merge-style collectors with scavenging spikes, and 1-3/4" diameter primary tubes. This package includes a direct bolt-in X-pipe with high flow cats. TIG-welded from aircraft-grade 304 stainless steel, these headers were constructed with smooth flow collectors as well as oval exhaust ports that are an exact match to the factory cylinder head.

High-Flow X-Pipe For A Raspy Race Car Tone

Mandrel-bent for increased flow to eliminate back-pressure and push out exhaust gasses faster than factory stock mid-pipes, ARH's X-Pipe was designed with the drag racer in mind. It's X design delivers a loud and raspy racing sound that makes your GT500 sound like it's packing some serious horsepower when you rev your engine.

ARH Dyno-Results: Up to +44 Horsepower Increase

Fits The Following Models: 2011-2014 Ford Mustang Shelby GT500 5.4L
