Factory Mounting Locations:
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.

Formed Collectors:
4-to-1 formed collectors decrease turbulence and increases exhaust velocity. The result is increased horsepower, torque and improved throttle response.

Heavy Duty Flanges:
3/8" thick 1-piece flanges prevent warpage to ensure a leak-free seal over the life of the vehicle.

Optimized Tube Lengths:
Tube lengths are optimized for true pulse control technology which improves flow and performance.
