Gibson Cat-Back Performance Exhaust 2002–2007 Chevy Silverado 1500 / GMC Sierra 1500 4.3L / 4.8L / 5.3L – Super Truck Aluminized – 5518

Gibson Super Truck Exhaust System – Unleash the Beast

Your truck deserves serious performance—and the Gibson Super Truck Exhaust System delivers just that. Designed for the boldest drivers, this high-performance system provides an aggressive race-rumble tone and a deep, powerful sound that turns heads. Dual tailpipes exit in front of the rear tires and feature premium T-304 polished stainless steel tips for unmatched durability and show-stopping style.

Engineered for maximum performance in the low-end power band (1800–3000 RPM), dyno testing proves real gains where it counts—10–15 horsepower and 15–20 lb-ft of torque—giving you stronger acceleration, better hill climbing, and more confident passing power.

At the heart of the system is the Gibson Superflow Muffler, featuring a baffled and chambered design with no internal packing. The result? A loud, aggressive exhaust note on the outside, with minimal interior drone inside the cabin.

Crafted from Heavy- Duty Aluminized tubing, this system is built to last and made for easy installation. It includes all necessary clamps and factory-style hangers for a 100% bolt-on setup—no welding required.

Proudly Made in the USA and backed by a Lifetime Limited Warranty.
