RAM 1500 Performance Exhaust - Flowmaster American Thunder Cat-Back (2009–2013). This system delivers a deep, muscular tone and durable stainless-steel construction for 5.7L Hemi and 4.7L models.

Built from 16-gauge mandrel-bent stainless tubing, it feeds a dual-outlet 50 Series HD performance muffler for a moderately aggressive exterior note with minimal cabin drone. Dual 2.50-inch tailpipes finish in polished 4.00-inch tips exiting straight out under the bumper. Uses factory hanger locations, clears the spare, and includes all necessary parts and hardware for straightforward at-home installation. Fits 2WD/4WD, all wheelbases, with rear-bumper exhaust cutouts; does not fit factory single-exit setups or 2019+ new body trucks. Covered by Flowmaster’s Lifetime Limited Warranty.
