Product details
This aluminized steel cat-back exhaust system fits 2003-2012 Dodge Ram 2500/3500 with the 5.7L Hemi engine, and also fits 2005-2008 Dodge Ram 1500 MegaCab with 5.7L engine. As an American Thunder system, it will provide improved performance and fuel economy while producing a moderate tone inside and outside the truck. Constructed from 16-gauge mandrel-bent aluminized steel tubing flowing into a Super 50 Series™ muffler. The dual 2.50-inch mandrel-bent tailpipes use the factory hanger locations for an easy installation. The system is finished off with a pair of polished 3.00-inch 304 stainless steel tips and comes with two sets of tailpipe exits giving you the option of two exit styles. Either straight out the back under the bumper, or out to the sides behind the rear wheels, which is ideal for towing applications. Easy to follow instructions and all necessary hardware is provided and the system is backed by our 3-year Limited Warranty. 2003-2008 Dodge Ram 2500, 3500 trucks with 5.7L engine.
