Take your vehicle’s performance to the next level with the Gibson Exhaust System. Engineered for maximum low-end torque and horsepower (1800–3000 RPM), it delivers dyno-proven gains of 10–15 horsepower and 15–20 lb-ft of torque, giving stronger acceleration, confident passing, and improved towing or hill climbing capabilities.

The Gibson Superflow muffler features a baffled and chambered design with no internal packing, producing an aggressive exterior tone while keeping interior drone minimal. Polished T-304 stainless steel tips exit straight out the back, offering a clean, stealthy look.

Built from heavy-duty 3-inch aluminized mandrel-bent tubing, this exhaust system ensures long-term durability. All necessary clamps and factory-style hangers are included for a hassle-free, 100% bolt-on installation—no welding required. Proudly made in the USA and backed by a Lifetime Limited Warranty, this system delivers performance, style, and reliability in one package.
