This system is meticulously designed for select makes and models, ensuring a perfect fit and superior functionality.

The Flowmaster 817523 Cat-Back 409S Single Rear Exit Exhaust System comes with fully adjustable mufflers that allow you to fine-tune the exhaust sound to your preference. The mufflers are equipped with Flowmaster's patented "Hush Powerflow Technology," which provides a unique balance between sound and performance.

This exhaust system is not only designed for performance but also for aesthetics. The polished stainless steel finish not only looks great but also protects the exhaust from the elements. Additionally, the system comes with black-coated tips, which add a stylish touch to the rear of your vehicle.
