Description

Overview

The Flowmaster Outlaw Extreme Cat-Back Exhaust System is engineered to give the 2019-2024 and 2026 RAM 1500 with the 5.7L engine a deep, powerful voice and improved exhaust performance. Built around Flowmaster’s proven Outlaw series muffler, this stainless steel cat-back setup delivers an aggressive sound while flowing more spent gases than a restrictive factory system, making it a smart upgrade for truck owners who want serious attitude paired with real capability.

At the heart of the system is 3.0-inch mandrel-bent 409 stainless steel tubing. Mandrel bending preserves the full diameter of the pipe through every curve, maximizing exhaust flow, while the 409 stainless construction stands up to heat, corrosion, and the demands of daily driving and off-road use alike.

Off-Road-Focused Design

What sets the Outlaw Extreme apart is its turndown-style dump exit positioned right after the muffler. By eliminating the over-axle tailpipe, this configuration improves ground clearance and departure angle — exactly what you want when the trail gets rough and every inch of clearance matters. The single tail pipe layout keeps the design clean and purpose-built for extreme situations, so your RAM 1500 breathes better and clears obstacles more confidently.

Sound & Performance

The included Outlaw series muffler is tuned for an aggressive tone, producing the deep, powerful note that has made the Outlaw name a favorite among truck enthusiasts. The center-inlet, center-outlet muffler measures 40.10 inches overall with a 3.00-inch outlet, working in concert with the mandrel-bent tubing to increase performance while announcing your presence with authority.
