Gibson 614434 Cat-Back Single Exhaust System Stainless Steel

The Gibson 614434 Cat-Back Single Exhaust System is a bolt-on performance upgrade engineered for maximum low-end power delivery. Designed to exit behind the rear tire, this single side exhaust system delivers measurable gains in acceleration, towing capacity, hill climbing, and passing power — all while maintaining a quieter in-cab experience compared to competing performance exhaust systems.

Dyno-tested results demonstrate peak torque and horsepower gains in the critical 1,800–3,000 RPM range, where everyday driving and towing demand the most. Expect average gains of 10–15 horsepower and 15–20 lb-ft of torque over stock.
