Gibson 619872 Cat-Back Single Exhaust System Swept-Side Stainless Steel

The Gibson 619872 is a cat-back single swept-side exhaust system constructed from 409L stainless steel with mandrel-bent tubing for smooth, unrestricted exhaust flow. Designed as a direct bolt-on replacement, this system delivers a noticeable boost in low-end power, making it an ideal upgrade for towing, hill climbing, acceleration, and passing performance.

At the heart of the system is a Gibson SuperFlow CFT stainless performance muffler featuring a straight-through design with internal baffles and chambers that maximize flow while minimizing backpressure. Dyno-tested results confirm maximum torque and horsepower gains in the critical low-end RPM range of 1,800–3,000 RPM, with average gains of 10–15 horsepower and 15–20 lb-ft of torque. The swept-side exit routes exhaust behind the rear tire for a clean, aggressive look.
