Wake up the power and performance of your 4.7L or 5.7L Hemi-powered 2009-2022* (classic body) RAM 1500 with this American Thunder Cat-back exhaust system. The system is fully constructed from 16-gauge mandrel-bent stainless steel tubing flowing into a 50 HD Series performance muffler with a single inlet/dual out for minimum drone in the cab, but with a moderately aggressive exterior tone. This custom system features dual 2.50-inch mandrel bent tailpipes with a pair of large 3.00-inch diameter polished stainless steel tips with your choice of exits, either dual out the side behind the wheels for towing, or exiting straight out the back under the rear bumper for a muscular look. The system includes all necessary parts and hardware required for an easy installation that you can do at home.
