This Force II® Cat-back stainless steel exhaust system is designed for 2011-2018 Chevrolet Silverado and GMC Sierra 1500 trucks with the 6.2L engine. Features include large 3.50-inch mandrel-bent tubing flowing into a Flowmaster 50 Series Big Block™ muffler for a muscular exterior sound, while the built-in Helmholtz chamber helps control the interior resonance. The system uses the factory hanger locations for an easy installation and is finished off with a highly polished 4.00-inch 304 stainless steel tip embossed with the Flowmaster® logo. This bolt-on system delivers noticeable performance gains while offering moderate interior and exterior sound levels and is covered by our Lifetime Limited Warranty.
