Corsa 2002-2006 GMC Sierra Denali Ext Cab/Short Bed 1500 6.0L V8 Polished Sport Cat-Back Exhaust

If you're looking to give your 2002-2004 GMC Sierra 1500 Denali Ext Cab/Short Bed with the 6.0L V8 engine a more aggressive sound and improved performance, this Corsa Sport cat-back exhaust system is a solid choice. This system is designed to replace your factory exhaust from the catalytic converter back, offering a noticeable change in both sound and flow.

Corsa's patented Reflective Sound Cancellation (RSC) technology is the heart of this system. It uses acoustic engineering to eliminate that annoying drone you often get at cruising speeds, while still letting you hear a deep, aggressive rumble when you step on the gas. The exhaust features a straight-through, mandrel-bent design with a 3.0-inch diameter, which allows for maximum airflow. This improved flow can lead to better performance and even a slight bump in fuel economy. The system exits on the single side with a polished, 4.0-inch slash-cut tip that looks sharp under the truck.

Installation is made easier because no welding is required, and detailed, full-color instructions are included. This cat-back system is made in the U.S.A. and comes with a 10-year limited warranty, giving you peace of mind with your investment.
