Flowmaster 6.2L F&R Cat-Back Exhaust For Chevy Silverado/GMC Sierra 1500 (07-19) (817602)

The Flowmaster American Thunder Cat-back exhaust system is a performance upgrade designed for 2011-2018 Chevrolet Silverado and GMC Sierra 1500 trucks equipped with the 6.2L engine. Constructed from stainless steel, this bolt-on system features a 3.50-inch mandrel-bent inlet pipe that directs flow into the 50 Series HD performance muffler, which has large 4.00-inch internals and a tuned resonance chamber to reduce interior drone. The system includes dual 2.50-inch mandrel-bent tailpipes that utilize factory hanger locations and are finished with large 3.50-inch polished stainless steel tips. It offers options for tailpipe exit locations—either out each side behind the rear tires for towing or straight out under the rear bumper for a more aggressive look. The system is covered by a Lifetime Limited Warranty and includes all necessary hardware for straightforward installation.

This exhaust system is compatible with 2011-2018 GM 1500 models, including 2WD and 4WD configurations, with Crew Cab/Short Bed (143.5" WB), Crew Cab/Standard Bed (153" WB), and Double Cab/Standard Bed (143.5" WB). It is ideal for drivers seeking an aggressive exterior sound while maintaining a moderate interior tone, suitable for street performance and daily driving. Designed as a bolt-on upgrade, it provides enhanced sound and performance without requiring extensive modifications. The included components and hardware facilitate easy installation at home, making it a practical choice for those looking to improve their truck’s exhaust note and appearance.
