Description

Flowmaster FlowFX Extreme exhaust systems deliver 409 stainless steel construction for extra durability and improved long-term corrosion resistance, plus a deep powerful sound and increased performance thanks to the FlowFX Series performance mufflers.

These cat-back exhaust system are built with 3.0 in. mandrel-bent 409 stainless steel tubing that help maintain maximum exhaust flow for better power and durability. They are designed with turndown-style dumps that exit right after the muffler eliminating the over-axle tailpipe. This elimination helps to improve ground clearance and departure angle when you are driving in more extreme off-road situations.

Flowmaster FlowFX Extreme exhaust systems use factory hanger locations, and all of the necessary hardware is included for an easy installation. The systems are backed by a Lifetime Limited Warranty.
