Gibson 617003 Cat-Back Single Exhaust System Stainless Steel

The Gibson Performance 617003 is a cat-back single exhaust system engineered to boost low and mid-range power output—exactly where it matters most for off-road driving, climbing, and towing. Constructed from 2.25-in. mandrel-bent 409 stainless steel tubing, this system delivers unrestricted exhaust flow while resisting corrosion for long-term durability. 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 fully welded design with no internal packing. This construction minimizes interior drone while producing a deep, aggressive exhaust note that won't fade over time.
