Gibson 07-12 Chevrolet Avalanche LS 5.3L 3in Cat-Back Single Exhaust - Stainless

Gibson has been making exhaust systems for trucks and SUVs for a long time, known for their focus on performance and durability. This particular cat-back system is built for your 2007-2014 Chevrolet Suburban 1500, 2007-2013 Chevrolet Avalanche, or 2007-2014 GMC Yukon XL 1500. It's designed to give your 5.3L engine a noticeable boost in power, especially where you need it most for towing or passing.

This system uses mandrel-bent stainless steel tubing for smooth exhaust flow, which helps the engine breathe better. The Superflow muffler is baffled and chambered, not packed, meaning it won't break down over time and helps reduce interior drone while still giving an aggressive sound outside. You can expect an average gain of 10-15 horsepower and 15-20 lb-ft of torque, with the biggest gains showing up in the low-end RPM range, perfect for getting heavy loads moving or accelerating quickly. The polished stainless steel slash-cut tips exit behind the rear tire for a clean look.

Installation is straightforward thanks to the bolt-on design, using factory-style hangers and including all necessary hardware, so no welding is required. Gibson backs this system with a Lifetime Limited Warranty, giving you peace of mind with your investment.
