Wake up the power and performance of your 5.7L Hemi-powered 2004-2005 Dodge 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 Series HD 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 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. Covered by our Lifetime Limited Warranty. Notes: Fits both 2 and 4 wheel drives models and all wheelbases.
