Gibson 617406 Cat-Back Single Exhaust System Stainless Steel

The Gibson 617406 is a cat-back single exhaust system constructed from 409 stainless steel mandrel-bent tubing, engineered to enhance low- and mid-range power output. Designed to boost performance from idle through 3,000 RPM, this system is well-suited for off-road driving, hill climbing, and towing applications. The exhaust exits straight out the rear and is finished with a polished T304 stainless steel slash-cut tip for a clean, aggressive look.

At the heart of the system is Gibson's Superflow baffled and chambered muffler — a packing-free design that delivers a deep, aggressive exhaust note while keeping interior drone to a minimum. All necessary mounting hardware and factory-style hangers are included for a straightforward bolt-on installation with no cutting or welding required.
