Description

The Flowmaster FlowFX Extreme Exhaust System is designed to enhance performance and exhaust tone. It features corrosion-resistant 409S stainless steel construction for durability, large-diameter, mandrel-bent tubing, and a high-flow FlowFX muffler for increased efficiency and a moderate-aggressive tone. It has a turn-down style exit for enhanced clearance and offers simple installation using factory hangers, with most applications requiring no cutting, drilling, or modifications. It is made in the USA and backed by a limited lifetime warranty.
