Gibson Exhaust 619705 Cat-Back Single Exhaust System Stainless Steel

The Gibson 619705 is a stainless steel cat-back single exhaust system engineered for maximum low-end performance. Dyno-tested to deliver peak torque and horsepower in the 1,800–3,000 RPM range, this system is purpose-built for improved acceleration, hill climbing, towing, and passing power — delivering average gains of 10–15 horsepower and 15–20 lb-ft of torque.

The system exits behind the rear tire and features Gibson's baffled and chambered Superflow muffler design, which minimizes interior drone while producing an aggressive exhaust tone. Because the muffler uses no internal packing, sound and flow characteristics remain consistent for the life of the system. Stainless mandrel-bent tubing maintains full pipe diameter through every bend, ensuring unrestricted exhaust flow and reduced backpressure.
