This system produced gains of up to +20 HP and +23 lbs. x Ft. Tq., as measured on our in-house dyno.

This system is constructed of 1-5/8 Inch mandrel-bent 304 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. These headers retain your stock catalytic converters and are a direct bolt-on installation which requires no cutting or drilling to provide a hassle-free installation.

Mitered collectors decrease turbulence and increase exhaust velocity. The result is increased horsepower, torque and improved throttle response. A Machined ball flange ensures a leak-free seal over the life of the vehicle.

100 percent Mig-Welded for race-proven strength and durability.
