Description
Overview
The Flowmaster Pro Series Outlaw Race Muffler was engineered to answer a growing challenge in motorsports: delivering serious power while keeping sound emissions in check. As more tracks across the country face pressure to regulate noise, the Flowmaster Engineering team returned to the drawing board with three clear goals — maximum power, maximum decibel reduction, and minimal weight. The result is a race muffler shaped by decades of Flowmaster involvement in racing and, quite literally, born at the track.
Built for competition first, the Pro Series Outlaw is ideal for all forms of motorsports where space and weight are at a premium but power can’t be compromised. It delivers surprisingly quiet operation, netting a reduction of approximately 8-10 decibels over open headers, and can be paired with a turndown for even further noise reduction. Whether you run methanol or gas, this muffler is designed to keep your program compliant without robbing performance.
Key Benefits
The philosophy behind the Pro Series Outlaw is simple: quiet the exhaust without choking the engine. That balance of decibel control and airflow makes it a smart choice for racers navigating tightening sound rules, and it works equally well as a standalone solution or as an addition to an existing exhaust system for further sound reduction without a loss of power.
- Approximately 8-10 dB reduction over open headers
- Aggressive sound level tuned for maximum power
- Lightweight design for weight-conscious race builds
- Compatible with methanol or gas engines
- 3.00-inch inlet diameter
- High-temperature paint finish built to handle race heat
- Can be run with a turndown for even quieter operation
Configuration & Fitment
This is a universal-fit race muffler, making it adaptable across a wide range of motorsports applications where a compact, lightweight sound solution is needed. It features a 3.00-inch inlet diameter and carries an emission code of 5, and it is intended for race vehicle use. Exhaust tips are sold separately, so you can finish the system exactly the way your build demands.
The high-temperature paint finish is chosen to stand up to the heat and demands of the track, and the Pro Series Outlaw’s flexibility means it can serve as a primary muffler or be added downstream of your current setup when you need to trim more decibels without giving up power. Choose the setup that matches your class rules, your space constraints, and your performance targets — the Pro Series Outlaw is designed to keep you fast and keep you legal at the tracks that matter most.
