Gibson 06-09 Chevrolet Trailblazer LT 4.2L 2.5in Cat-Back Single Exhaust - Stainless

Gibson is known for making well-built exhaust systems that offer a noticeable difference in performance. This particular cat-back system is designed specifically for your 2006-2009 Chevrolet Trailblazer LT with the 4.2L engine, and it's built to give you that extra edge when you need it most. Whether you're hauling a trailer, climbing a steep grade, or just need a bit more power for passing, this system is engineered to help.

You can expect improved acceleration and a solid boost in torque and horsepower, especially in the lower RPM range where it matters for towing and everyday driving. Gibson's dyno tests show gains of around 10-15 horsepower and 15-20 lb-ft of torque. They've achieved this with a baffled and chambered muffler that doesn't rely on internal packing, which helps keep the sound aggressive outside but remarkably quiet inside your cabin, minimizing drone. The tubing is made from stainless steel and is mandrel-bent to ensure smooth airflow, and it exits behind the rear tire with a polished stainless steel slash-cut tip for a clean look.

Installation is straightforward thanks to the bolt-on design, which uses factory-style hangers and includes all the necessary hardware, so no welding is required. This system is backed by Gibson's Lifetime Limited Warranty, giving you peace of mind with your purchase.
