Enhance performance and clearance with durable stainless steel construction.
The Flowmaster American Thunder cat-back exhaust system is engineered for those seeking improved performance and off-road capability. This system replaces the factory transverse muffler, relocating the Super HP-2 muffler behind the catalytic converter to deliver a moderate to aggressive sound profile. Constructed from durable 409S stainless steel, the 2-1/2 inch mandrel-bent tailpipe is designed for maximum ground clearance, making it suitable for off-road driving.
Featuring a polished 3 inch stainless steel tip, the exhaust system is designed to be tucked high under the rear bumper, ensuring optimal clearance. The installation process is straightforward, utilizing factory hanger locations and requiring no welding, which allows for a home installation in approximately two hours. This system includes all necessary parts and hardware, making it a comprehensive solution for enhancing your vehicle's exhaust performance.
With its Super HP-2 laminar flow technology, this exhaust system not only improves sound but also enhances exhaust flow efficiency. The single exhaust design with a single exit on the passenger side rear provides a clean and aggressive look while maintaining functionality. The Flowmaster American Thunder cat-back system is a robust choice for those looking to elevate their vehicle's exhaust system.
