Description
Overview
The Flowmaster American Thunder Cat-back Exhaust System is built for the driver who wants a serious upgrade in tone and durability without sacrificing everyday comfort. Engineered from heavy 16-gauge mandrel-bent aluminized steel tubing, this cat-back system is designed to deliver an aggressive exterior sound paired with a moderate interior tone that keeps conversations in the cab easy and enjoyable. It’s the ideal balance for anyone who wants to be heard on the outside without being overwhelmed on the inside.
Sound & Performance
At the heart of this system is an aluminized steel Super 50 Series performance muffler (part number 530552), tuned specifically for that deep, aggressive exterior note combined with a refined interior tone. The mandrel-bent construction promotes smooth exhaust flow for maximum performance, while the heavy-gauge aluminized steel tubing is chosen for long-term durability against the elements.
Dual Tailpipe Configuration
The American Thunder system features dual 2.50-inch tailpipes that clear the factory spare tire and give you two exit options. 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. Each system is finished with a pair of highly polished 304 stainless steel tips embossed with the Flowmaster name, adding a clean, aggressive appearance that matches the sound.
