Description
Overview
The Flowmaster Flow FX Extreme Cat-Back Exhaust System delivers a deep, powerful tone and improved exhaust flow for your RAM 1500. Built around a Flow FX series muffler, this stainless steel cat-back system is engineered to boost performance while unleashing the aggressive sound that Flowmaster is known for. It’s a purpose-built upgrade for truck owners who want more sound, more flow, and better off-road capability from a system designed to bolt on using factory mounting locations.
At the heart of the system is 3.0-inch mandrel-bent 409 stainless steel tubing, chosen for maximum exhaust flow and long-term durability. The mandrel bends keep the internal diameter consistent through every curve, helping exhaust gases evacuate freely for increased performance. The Flow FX muffler measures 40.10 inches in overall length with a center inlet, center 3.00-inch outlet, and a silver finish that matches the silver pipe tubing.
Built for Extreme Duty
What sets the Flow FX Extreme apart is its turndown-style dump exit positioned right after the muffler. By eliminating the over-axle tailpipe entirely, this configuration improves ground clearance and departure angle—exactly what you need when the driving gets more extreme and off-road. Fewer pipes underneath the truck means less to catch on obstacles and a cleaner, more purposeful setup for trail and work duty alike.
