This system produced gains of up to +14 HP and +15 lbs. x Ft. Tq., as measured on our in-house dyno.

This system is constructed of 1-5/8 Inch mandrel-bent 409 stainless steel tubing for maximum strength and durability. Factory style laser cut machined mild steel flanges are used used for a secure leak-free seal. 3-to-1 Mitered Merge collectors decrease turbulence and increases exhaust velocity.

The result is increased horsepower, torque and improved throttle response. Includes gaskets and lower outlet hardware for a direct bolt-on system. No cutting or modifications required for a hassle-free installation.

Utilizing state-of-the-art computer-aided design technology, these headers are designed for custom, high tolerance factory fitment. 100 percent Mig-Welded for race-proven strength and durability.
