Overview

Factory Mounting Locations:
Utilizing factory mounting locations, this Y-pipe features a direct bolt-on installation which requires no cutting or drilling.

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

Ball Socket Connections:
Unique ball socket connections are used for an easy installation. The ball socket connections also require no gaskets, giving you a leak-free seal.

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

Note:
Headers and Y-pipe are sold as set, not available individually.
