Gibson 618602 Cat-Back Single Exhaust System Stainless Steel with Polished Slash-Cut Tip

The Gibson 618602 Cat-Back Single Exhaust System is Gibson's top-performing stainless steel exhaust, engineered and dyno-proven to maximize low-end power output. Designed for improved acceleration, towing, hill climbing, and passing performance, this system delivers real-world gains where drivers need them most — in the 1,800 to 3,000 RPM range. Average performance improvements include 10–15 horsepower and 15–20 lb-ft of torque. The swept-side exit routes exhaust behind the rear tire, keeping cabin noise lower than competing performance exhausts while still delivering a deep, aggressive exhaust tone.
