Corsa 2011-2013 GMC Sierra Ext. Cab/Std. Bed 1500 6.2L V8 Black Sport Cat-Back Exhaust

If you're looking to give your 2011-2013 GMC Sierra 1500 with the 6.2L V8 engine a more aggressive sound and better performance, this cat-back exhaust system from CORSA is a solid option. It's designed to replace your factory exhaust from the catalytic converter back, giving you a more direct path for exhaust gases to exit the vehicle.

CORSA uses their patented Reflective Sound Cancellation (RSC) technology to tune the exhaust note. This means you get a powerful, aggressive sound when you accelerate, but it quiets down to a drone-free experience when you're cruising at a steady speed. The system is constructed from 304 stainless steel for durability and features twin 4.0-inch black PVD Pro-Series tips for a sharp look. It's designed to flow about 60 percent better than the stock exhaust, which can help with engine performance.

Installation is a bolt-on affair, meaning no welding is required, and it's lighter than the original equipment. This system is a single side exit, tucked up neatly behind the rear tire. It comes with detailed instructions, and full-color versions are available online to help guide you through the process.
