Gibson Performance Exhaust 619999 Cat-Back Single Exhaust System - Stainless Steel

The Gibson Performance Exhaust 619999 is a cat-back single swept-side exhaust system crafted from stainless steel mandrel-bent tubing. Engineered and dyno-tested to deliver improved acceleration, enhanced towing capacity, better hill climbing, and stronger passing power, this system is designed for drivers who demand real performance gains.

Gibson's proprietary Superflow™ muffler technology uses resonance chambers, directional louvered tuning ports, and angular induction to draw exhaust gases through the system and expel them at higher velocity — maximizing power output throughout the RPM range. Dyno testing confirms peak torque and horsepower gains in the critical 1,800–3,000 RPM range, with average increases of 10–15 horsepower and 15–20 lb-ft of torque. Fuel economy may also improve as the engine operates more efficiently.

The baffled and chambered muffler design delivers an aggressive exhaust note outside the vehicle while remaining notably quiet inside the cab. The system exits behind the rear tire for a clean, factory-integrated look.
