Overview

The Flowmaster Outlaw Series Race Muffler is a purpose-built, compact performance muffler engineered for competition use where a muffler is required but no set sound reduction rule applies. As part of Flowmaster’s aggressive Outlaw lineup, this 3.00 inch “Shorty” race muffler delivers the raw, unmistakable exhaust note that serious racers demand, all from a remarkably small package that fits tight builds and demanding chassis layouts.

Measuring just 6.50 inches long with a 4.00 inch diameter body, the Outlaw “Shorty” is designed to save critical space under aggressive race vehicles without sacrificing the deep, loud character that defines the Outlaw name. When you need maximum sound and minimal footprint, this muffler is built to perform.

Built for the Track

Constructed from durable 409S Stainless Steel, the Outlaw Race Muffler stands up to the heat and abuse of race conditions. A high-temperature paint finish adds an extra layer of protection where it matters most, helping the muffler look the part while enduring the demands of competition. With a 3.00 inch inlet, it’s ready to integrate into high-flow exhaust systems where airflow and volume are priorities.

Please note that exhaust tips are sold separately, allowing you to complete your setup with the tip configuration that best suits your vehicle and personal style.
