This stainless steel American Thunder® cat-back exhaust system fits 2014-2020 RAM 3500 Crew Cab and Mega Cab trucks with the 6.4L Hemi engine. As a Flowmaster® 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 409 stainless steel tubing, the 3.50-inch inlet pipe flows into a 50 Series HD™ muffler for a deep moderate performance tone. The dual 3.00-inch mandrel-bent tailpipes utilize the factory hanger locations for an easy installation and the system is finished off with a pair of large 4.00-inch polished 304 stainless steel tips. The system comes with two sets of tailpipe exits giving you the option of either exiting straight-out the back under the bumper or out the sides behind the rear wheels, which is ideal for towing applications. Includes easy to follow instructions and all necessary hardware and is covered by our Lifetime Limited Warranty. Notes: Fits 2 & 4 Wheel Drive trucks with single or dual rear wheels and 149.5, 160 & 168.9-inch Wheelbases.
