Product Details

If you're looking to give your 1999-2007 Chevrolet Silverado or GMC Sierra 1500/2500 a more aggressive sound and a noticeable boost in performance, this Gibson Super Truck cat-back exhaust system is a solid choice. Designed specifically for trucks with the 4.3L engine, this system replaces your factory exhaust from the catalytic converter back, giving you a deep, powerful rumble that you can hear without it being overwhelming inside the cabin. You can expect a more responsive throttle and improved acceleration thanks to the free-flowing design.

This Gibson system features a baffled/chambered muffler with no internal packing, which contributes to its aggressive sound and the Superflow design that helps increase horsepower and torque. Dyno tests show average gains of 10-15 horsepower and 15-20 lb-ft of torque. The tubing is made from aluminized steel, which offers good corrosion resistance for the price, and it's mandrel-bent to ensure consistent exhaust flow. The dual tailpipes exit in front of the rear tires and are finished with stainless steel clampless sport tips, giving your truck a custom look. Installation is designed to be straightforward with a bolt-on process, meaning no welding is required, and all the necessary hardware is included for a hassle-free setup.

While this system is built for performance and sound, it's important to note that it's not recommended for towing applications and the noise level may exceed 95 decibels. Gibson backs this exhaust system with a Lifetime Limited Warranty, giving you peace of mind with your purchase. This is a well-built system that offers a significant upgrade over your stock exhaust for trucks like the 2005 Chevrolet Silverado 1500 or the 2003 GMC Sierra 1500.
