- Description: Flowmaster's® American Thunder Cat-back true dual exhaust system for the 2025 - 2026 RAM 1500 with the 3.0-liter Standard and High Output engines gives you a great way to customize your RAM 1500 to your personality. This performance exhaust system fits both 2/4 Wheel drive models and is manufactured from 409 stainless steel for years of trouble-free service and performance. Features include dual 3.00-inch inlet pipes leading into a custom tuned 409 stainless steel American Thunder series muffler for great sound and maximum performance. This Cat-back system includes Flowmaster’s exclusive Scavenger X-Pipe with our D-Port technology for maximum exhaust pulse velocity and helps to create a deep exhaust tone. The dual 3.0-inch mandrel-bent tailpipes exit in the stock location in the factory bumper cut outs with 4.5-inch black ceramic coated tips. Included in the tailpipe assemblies are tuned resonators that help maintain a comfortable experience in the cab. On Standard Output models this system turns the exhaust into a true dual style system like the High Output and RHO models. This will allow for better overall performance gains and will work better with any future engne modifications. Max dyno gains of 35 hp and 33 lb-ft at the rear wheels (HO models) deliver power you can feel! The system uses all the factory hanger locations and connections for an easy installation that you can do at home. Kits include installation instructions and all necessary hardware.
