Product information
Overview
This Force II® Cat-back exhaust system is specifically designed for 2011-2019 GM Silverado/Sierra 2500HD/3500HD crew cab/short bed trucks with the 6.0L engine. This emissions legal system is constructed from 3.50-inch mandrel-bent stainless steel tubing flowing into a 50 Series Big Block™ performance muffler for a mild to moderate tone inside and moderate sound level outside the truck. The tailpipe exits behind the right rear tire, which is ideal for towing applications, and is finished off with a large 4.00-inch polished stainless steel tip. The system uses the factory hanger locations making for a quick and easy installation. Includes all necessary parts, hardware, and detailed instructions for an easy installation you can do at home. Covered by our Limited Lifetime Warranty. Note: Fits 2 and 4 wheel drive Crew Cab models with the 6.5ft bed.
