Gibson 65402 Cat-Back Dual Extreme Exhaust System - Stainless Steel

The Gibson 65402 Cat-Back Dual Extreme Exhaust System is engineered for drivers who demand aggressive performance sound, bold dual-outlet styling, and real-world horsepower gains. Built from 3-inch 409 stainless mandrel-bent tubing, this bolt-on system exits behind each rear tire at an aggressive angle for a commanding, head-turning look.

The system installs without welding and includes all necessary hardware and factory-style hangers for a straightforward, direct-fit installation.
