The Flowmaster® American Thunder® Cat-Back Exhaust System is engineered for 2014-2024 RAM 3500 Crew Cab and Mega Cab trucks with the 6.4L HEMI engine, including single or dual rear wheel configurations. This bolt-on, emissions-legal system improves performance and fuel economy while providing an aggressive exterior and moderate interior sound.

Constructed from 16-gauge mandrel-bent 409 stainless steel tubing, the 3.50-inch inlet flows into a 50 Series HD™ performance muffler for a deep, refined tone. Dual 3.00-inch mandrel-bent tailpipes offer two exit configurations: straight out the rear bumper for a muscular look or out the sides behind the rear wheels, ideal for towing. Finished with large 4.00-inch polished 304 stainless steel tips embossed with the Flowmaster logo, this system uses factory hanger locations for an easy installation and comes with all necessary hardware and instructions. Covered by Flowmaster’s Lifetime Limited Warranty.
