Product details
The American Thunder® cat-back exhaust system for 2014-2024 Ram 2500 trucks is perfect for the person looking for moderately aggressive interior and aggressive exterior sound levels, with all of the performance benefits that you would expect from Flowmaster®. This bolt-on emissions-legal system fits the Crew Cab Standard Bed/Long Bed and Mega Cab models with a 6.4L engine and coil spring rear suspension. The system features a stainless steel 50 Series HD™ muffler with large 4.00-inch internals. The large dual 3.00-inch stainless steel tailpipes are mandrel-bent to reduce restrictions and maximize performance. The kit has two options for tailpipe exits, either out the sides behind the rear wheels for towing, or straight out the back under the rear bumper. They are finished off with a pair of large 4.00-inch polished stainless steel tips. The exhaust system is covered by our Lifetime Limited Warranty and includes all necessary parts, hardware and easy to follow installation instructions. Note: Fits 149.4, 160.5 and 169.4-inch wheelbases. Does not fit trucks with the optional factory airbag suspension. Fits 2014-2024 Ram 2500 with 6.4L Hemi engine. - Aggressive to moderate sound Flowmaster American Thunder Cat-back Exhaust System
