To eliminate flow blockage 3-to-1 formed collectors are used on the headers to decrease turbulence and increase exhaust velocity for maximum performance. The high-flowing Y-pipe is designed using 400 cell catalytic converters and 2-1/2” mandrel-bent, stainless steel tubing for optimum flow resulting in added horsepower and torque. This system is designed to fit as a combo with all components supplied for a hassle-free installation with no modifications necessary.

Long Tube Headers
Formed Collectors:
3-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.

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

Dual High Flow Catalytic Converters:

This system utilizes 400 CPSI (cell per square inch) catalytic converters 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 2-1/2" stainless steel tubing and utilizes a mitered merge collector to eliminate dead space that can cause turbulence and hinder flow.

409 Stainless Steel Construction:
Constructed out of durable CNC mandrel bent 409 stainless steel tubing for maximum performance, corrosion resistance and strength.

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.

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.

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