Gibson 618200 Cat-Back Single Exhaust System Stainless Steel

The Gibson 618200 is a cat-back single exhaust system constructed from 409 stainless steel mandrel-bent tubing, designed for truck owners seeking a meaningful boost in low-end power with a deep, aggressive exhaust tone. Dyno testing confirms peak torque and horsepower gains in the 1800–3000 RPM range, with average increases of 10–15 horsepower and 15–20 lb-ft of torque—right where it matters most for towing, hauling, and everyday driving.

At the heart of the system is Gibson's Superflow muffler, featuring a baffled and chambered internal design with no internal packing. This construction minimizes interior drone while delivering a bold exterior sound. The exhaust exits cleanly behind the rear tire for a clean, factory-style appearance.
