Description
Overview
The Flowmaster American Thunder Cat-back Exhaust System is engineered for drivers who want a serious upgrade in sound and flow without the drone that makes long drives miserable. Built from heavy 16-gauge mandrel-bent aluminized steel tubing, this complete cat-back system delivers the durability and maximum performance Flowmaster is known for, while striking the ideal balance between an aggressive exterior tone and a moderate interior tone.
At the heart of the system is the aluminized steel Super 50 Series performance muffler (part# 530552). This muffler is tuned to produce a deep, aggressive sound outside the vehicle while keeping the cabin comfortable enough to hold a conversation. If you’ve ever wanted big exhaust attitude without being driven out of the cab, this is the blend the American Thunder series was designed to hit.
Key Benefits
With a 2.50-inch inlet diameter and dual 2.50-inch tailpipes, the system is designed to move exhaust efficiently. The dual tailpipes are routed to clear the factory spare tire and give you two exit configurations to choose from: straight out the back for a true dual look, or exiting out each side behind the rear wheels, which is ideal for towing. Whichever setup fits your driving style, both are supported by the same complete kit.
Every system is finished with a pair of highly polished 3.00-inch 304 stainless steel tips embossed with the Flowmaster name, adding a premium visual accent that stands up to the elements. U-bolt clamping and all necessary parts, hardware, and instructions are included, making this a straightforward installation you can tackle at home.
