Gibson 04-12 Chevrolet Colorado/GMC Canyon (Regular Cab) Cat-Back Single Exit Exhaust

This Gibson cat-back exhaust system is made for your 2004-2006 Chevrolet Colorado or GMC Canyon regular cab. It's designed to replace your factory exhaust from the catalytic converter back, exiting behind the rear tire with a single polished stainless steel tip. If you're looking to get more out of your truck's engine, especially when you need it most for towing or climbing hills, this system can help.

Gibson's engineers focused on making this system perform well across the board, but they saw notable gains in low-end torque and horsepower, typically between 1800 and 3000 RPM. Dyno tests show an average increase of 10-15 horsepower and 15-20 lb-ft of torque. The Superflow muffler uses baffles and chambers instead of internal packing, which helps it flow better while keeping the sound more controlled inside the cab, minimizing drone. The tubing is mandrel-bent stainless steel to ensure consistent diameter and smooth airflow, and it all comes together with a polished slash-cut tip.

Installation is intended to be a straightforward bolt-on process, using factory-style hangers and including all the necessary hardware, so no welding is required. This system is built from stainless steel for durability and is backed by a lifetime limited warranty from Gibson.
