Gibson 03-05 Chevrolet Trailblazer LS 4.2L 2.5in Cat-Back Single Exhaust - Stainless

If you're looking to get more out of your 2003-2005 Chevrolet Trailblazer LS with the 4.2L engine, especially when it comes to hauling or climbing hills, this Gibson cat-back exhaust system is a solid option. It's designed to help your truck accelerate better and gain more power where you'll feel it most, like at lower RPMs. You can expect noticeable gains in both horsepower and torque, making towing and passing feel more confident.

This system is built with mandrel-bent stainless steel tubing for consistent flow and durability, and it features a Superflow muffler that's baffled and chambered to keep the sound aggressive outside without creating excessive drone inside the cab. The polished stainless steel slash-cut tip exits behind the rear tire for a clean look. Gibson designed this to be a hassle-free, bolt-on installation, meaning no welding is required, and it uses factory-style hangers for a straightforward fit. It's backed by a lifetime limited warranty, so you can be confident in its longevity.
