Flowmaster Pro Series Muffler Overview
The Flowmaster Pro Series Muffler is a purpose-built performance muffler engineered for enthusiasts who demand serious flow without giving up drivability. As part of the respected Flowmaster exhaust family, the Pro Series carries forward the reputation the Flowmaster company earned across street, strip, and off-road applications. Whether you’re building a street rod, upgrading a diesel work truck, or dialing in a dedicated race car, this Flowmaster muffler is designed to deliver big airflow and a controlled, purposeful tone.
Flowmaster developed the Pro Series with the dyno and the track as the proving ground. During testing, these Flowmaster mufflers consistently delivered performance that is equal to or surpasses open pipe systems, while dramatically reducing sound levels across the entire RPM range. That means you get the aggressive, unrestricted flow character of open pipes with a moderate sound level that keeps things civil at cruise and under load.
Built for Every Application
One of the standout traits of the Pro Series is its versatility. Flowmaster Inc. designed these mufflers to work on virtually any build, from street trucks and diesel pullers to RV pushers, plus every class of racing on dirt or asphalt. With a universal fitment and a generous 4.00-inch inlet diameter, the Pro Series is ready to handle high-volume exhaust flow on demanding, high-output combinations where lesser mufflers become a restriction.
Key Highlights
- Pro Series design that meets or exceeds open pipe performance in Flowmaster testing
- Dramatically reduced sound levels across the RPM range for a moderate, refined tone
- Large 4.00-inch inlet diameter to support high-flow, high-horsepower and diesel applications

Finish & Configuration
Each Pro Series muffler is protected by a high-temperature paint finish that stands up to the heat generated by a hard-working exhaust system. This is a muffler-only component, so exhaust tips are sold separately, giving you the freedom to complete your Flowmaster exhaust system exactly the way you want it. That flexibility makes the Pro Series an ideal centerpiece for a custom build where flow, sound, and appearance all matter.
If you’ve been searching for the best muffler to anchor a high-performance combination, the Flowmaster 40 Series and Flowmaster FX lines have long set the standard for tone and flow — and the Pro Series extends that legacy to the most demanding street and competition applications. Please note the California Proposition 65 warning and emission code 5 associated with this product. Trust Flowmaster to deliver the flow, durability, and sound control your build deserves.
