Product Details
Gibson is known for making well-built exhaust systems that improve your truck's performance. This cat-back system is specifically made for your 2014-2018 Chevrolet Silverado 1500 with the 5.3L engine. It's designed to give you a noticeable boost in acceleration, especially when you're climbing hills, towing, or passing. You'll feel the difference in torque and horsepower right where you need it most, between 1800 and 3000 RPM.
This system features a 3.5-inch diameter aluminized, mandrel-bent tubing for smooth exhaust flow. The Superflow™ muffler is baffled and chambered, not packed, which helps it perform better and keeps the sound aggressive outside while minimizing interior drone. Dyno tests show an average gain of 18-21 horsepower and 20-22 lb-ft of torque. The exhaust exits behind the rear passenger tire, and it comes with polished stainless steel slash-cut tips for a clean look. Installation is straightforward with a bolt-on design that uses factory-style hangers, so no welding is required.
This cat-back system includes all the necessary hardware for an easy installation. Gibson backs this exhaust with a Lifetime Limited Warranty, giving you peace of mind.
