Mitered Collectors

3-to-1 mitered merge collectors decrease turbulence and increase exhaust velocity. The result is increased horsepower, torque and improved throttle response.

Heavy Duty Flanges:

3/8" thick flanges prevent warpage to ensure a leak-free seal over the life of the vehicle.

Optimized Equal Tube Lengths:

Each primary tube was specifically engineered and tuned at equal lengths for optimum efficiency resulting in improved torque and performance.

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.

aFe headers are engineered and manufactured in our Corona, California manufacturing facility.
