Description

Overview

The Flowmaster Outlaw Series Race Muffler is built for enthusiasts who want maximum exhaust flow and an unmistakably aggressive tone. Engineered as a universal-fit muffler, it can be connected directly to your header collectors or dropped into an existing exhaust system, giving you the flexibility to run it in a purpose-built race setup or a street-driven late model muscle car. When you want your exhaust to breathe hard and sound the part, the Outlaw delivers.

Flowmaster developed the Outlaw platform specifically for racing applications where a muffler is required but there is no set decibel limit to meet. That focus shows in its unapologetically loud, aggressive sound level — this is a muffler that announces its presence rather than muting it. With a 3.00-inch inlet diameter and a high-temperature paint finish designed to stand up to the heat of hard use, it’s ready for demanding performance conditions.

Key Benefits

The Outlaw Series is engineered around straightforward, high-performance priorities: move exhaust gases efficiently, produce a bold exhaust note, and hold up under sustained heat. Its universal design makes it a versatile choice for a wide range of builds, whether you’re fabricating a full custom system or upgrading the muffler on an established setup.

  • 3.00-inch inlet diameter for strong exhaust flow
  • High-temperature paint finish built to withstand exhaust heat
  • Universal fitment — connect directly to header collectors or add into an existing system
  • Aggressive sound level tuned for racing applications with no set decibel limit
  • Part of Flowmaster’s dedicated Outlaw muffler series
  • Emission Code 5 designation

Configuration & Installation Notes

Because the Outlaw is designed as a universal muffler, it adapts to a variety of exhaust layouts. Mounting uses new hangers, which are not included, so plan to source the appropriate hardware for your specific vehicle and exhaust routing. Exhaust tips are also sold separately, letting you finish the system exactly the way you want. This modular approach makes it easy to build a system tailored to your goals rather than settling for a one-size-fits-all package.

Fitment

This muffler carries a universal fitment and is well suited to late model muscle car applications as well as dedicated racing builds. Whether you’re piecing together a track-focused exhaust from the header collectors back or swapping the muffler in your current setup, the Outlaw’s flexible design and 3.00-inch inlet make it an adaptable choice. As with any universal component, confirm your inlet and outlet dimensions and available space before installation.

For drivers who want a muffler that flows freely and makes no apologies for its volume, the Flowmaster Outlaw Series Race Muffler is engineered to perform where sound restrictions don’t apply.
