Long Tube Headers:
The headers are designed to retain the factory air injection giving you provisions for all factory emissions equipment.
4-to-1 formed collectors decrease turbulence and increases exhaust velocity. The result is increased horsepower, torque and improved throttle response.
Laser-Cut Header Flanges:
High quality laser-cut header flanges provides superior sealing at the head surface.
Connection Pipes (Race):
Performance and Sound:
This system was designed as a "Race Only" version for added performance and a more aggressive sound.
