Overview

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.

Y-Pipe
Construction:

Constructed of mandrel-bent 3" stainless steel piping which transitions into single 3-1/2" piping to reduce back pressure and improve flow.

True Merge Collectors:
Eliminates dead space that can cause turbulence and hinder flow that formed collectors are prone to produce.

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 fit in the stock location incorporating the OE hanger, flange and O2 sensor locations.
