The American Thunder® Cat-back exhaust system for 2011-2018 Chevrolet Silverado and GMC Sierra 1500 trucks with the 6.2L engine, is perfect for the person looking for an aggressive exterior sound level while maintaining a moderate interior tone. This bolt-on stainless steel system features a 3.50 in. mandrel-bent inlet pipe flowing into the 50 Series™ HD performance muffler with large 4.00 in. internals and a built-in tuned resonance chamber to minimize interior drone. The system has dual 2.50 in. mandrel-bent tailpipes which use the factory hanger locations and are finished off with large 3.50 in. polished stainless steel tips. This exhaust system gives you choices for tailpipe exit location either out each side behind the rear tires if you do a lot of towing, or straight-out under the rear bumper for a muscular look. The exhaust system is covered by our Lifetime Limited Warranty and includes all necessary parts and hardware for easy installation you can do at home. Note: Fits 2/4 WD model with Extended Cab standard bed and Double Cab with 5.5-ft bed.

  • 50 Series HD Performance Muffler
