Product Details

The Gibson 615610 Cat-Back Single Side Exhaust System is engineered for drivers who demand more from their vehicle. Built with a baffled and chambered muffler design, this stainless steel system delivers an aggressive exhaust note while keeping interior cabin noise to a minimum — quieter than comparable performance exhaust systems. The system exits behind the rear tire for a clean, factory-integrated appearance.

Dyno-tested results demonstrate maximum torque and horsepower gains concentrated in the low-end RPM range (1,800–3,000 RPM), making this system ideal for acceleration, hill climbing, towing, and passing. Average gains of 10–15 horsepower and 15–20 lb-ft of torque make this Gibson's best-performing exhaust system in its class.
