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

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

OE Bung and Sensor Location:
This system retains all factory O2 sensor locatios for easy installation.

Dual High Flow Catalytic Converters:
This system utilizes 400 CPSI (cell per square inch) catalytic converters are used for maximum flow.

Constructed of mandrel-bent 3″ stainless steel piping to reduce back pressure and improve flow.

True Merge Collectors:
The y-pipe is designed using 3″ to 3-1/2″ transition for optimum flow and utilizes a mitered merge collector to eliminate dead space that can cause turbulence and hinder flow.

Leak-Free Seal:
High quality OE style flanges and band clamps are used for a complete 360 degree sealing surface.

Hassle-Free Installation:
The performance header and y-pipe are designed to be a true bolt on system with no cutting or modifications required.

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

Note: This system is not currently CARB exempt and is not available for sale in California or for use on any vehicle registered with the California Department of Motor Vehicle.
