Description
Overview
The Flowmaster American Thunder Cat-back Exhaust System is built for the driver who wants a serious upgrade in tone and flow without sacrificing everyday comfort. Engineered with heavy 16-gauge mandrel-bent aluminized steel tubing, this system is designed to deliver durability and maximum performance mile after mile. It’s the ideal choice if you’re after an aluminized steel cat-back with an aggressive exterior tone and a more moderate interior character that keeps the cabin livable.
At the heart of the system is the Super 50 Series performance muffler (part number 530562), which strikes that perfect balance Flowmaster is known for: a deep, aggressive sound outside the vehicle paired with a moderate interior tone that won’t drive you out of the cab when you’re carrying on a conversation. With a 3.00-inch inlet feeding the muffler and dual 2.50-inch tailpipes downstream, this cat-back is engineered to move air efficiently while sounding the part.
Key Benefits
The dual tailpipe design clears the factory spare tire and gives you two choices of exit locations. Route them straight out the back for that true dual look, or exit out each side behind the rear wheels — an ideal setup for towing. Whichever configuration suits your build, the system is finished with a pair of highly polished 304 stainless steel tips embossed with the Flowmaster name for a clean, unmistakable look at the bumper.
