American Thunder Cat-Back Exhaust for 2025 RAM 1500 3.0L Hurricane 818199 By Flowmaster

Let your RAM 1500 breathe like it just hit the gym. The Flowmaster American Thunder Cat-Back True Dual Exhaust System for the 2025 RAM 1500 (3.0L Standard and High Output engines) brings serious growl, extra power, and enough attitude to make your neighbors “accidentally” drop their coffee mugs every morning.

This system is all about boosting performance and personality without requiring an engineering degree. Designed to fit both 2WD and 4WD models, it’s built from rugged 409 stainless steel that laughs in the face of rust. The dual 3-inch mandrel-bent pipes route through a tuned American Thunder muffler, which is basically Flowmaster’s way of saying “here’s your new favorite noise.”

The real magic happens with the included Scavenger X-pipe and D-Port tech, which optimize exhaust flow like a caffeinated traffic cop—efficient and surprisingly loud. You also get 4.5-inch black ceramic-coated tips exiting clean through the stock bumper cutouts, adding that “I definitely don’t drive this thing to yoga” look.

On Standard Output models, this kit even transforms your setup into a true dual system, just like the High Output and RHO versions. That means you’re ready for future mods—and even more muscle down the line. Max gains hit 35 horsepower and 33 lb-ft of torque at the wheels (on HO models), which is enough to make your truck feel like it drank an energy drink and hit the open road.

Everything bolts up using stock hangers, and it’s all backed by Flowmaster’s Lifetime Limited Warranty. So go ahead—install it in your driveway, crank it up, and enjoy the sound of thunder… American Thunder.
