Flowmaster GM 1500 5.3L Force II SS Cat-Back For 99-13 (817492)

The Flowmaster Force II cat-back exhaust system is designed for 2007–2013 GM Silverado and Sierra 1500 models equipped with a 5.3L engine. Constructed with 3.00-inch mandrel-bent stainless steel tubing, it directs exhaust flow into a Super 50 Series muffler, providing a mild interior tone and a deep, moderate sound outside the vehicle. The system features dual 2.50-inch stainless steel tailpipes that utilize factory hanger locations and can be configured with either straight-out-the-back or side exit options, the latter ideal for towing applications. Finished with large 3.00-inch polished dual-wall stainless steel tips, it offers a durable, emissions-legal upgrade that enhances sound and performance. The kit includes all necessary hardware for straightforward installation and is backed by a Lifetime Limited Warranty.

This bolt-on system fits all 2007–2008 GM 1500 models (excluding classic body styles) with 4.8L or 5.3L engines, as well as 2009–2013 GM 1500 Extended Cab models with 5.3L engines, including 6.5-ft beds and Crew Cabs with 5.5-ft beds. It is designed for direct replacement and easy installation, providing improved exhaust flow, sound, and a performance upgrade suitable for street and daily driving. The system’s configuration options allow for personalized exit locations, enhancing the truck’s appearance and acoustics while maintaining emissions compliance.
