Description
The Flowmaster Pro Series Muffler is engineered to deliver maximum exhaust performance while maintaining a controlled and moderate sound level. Designed to work across a wide range of applications, the Pro Series is suitable for street vehicles, classic muscle cars, diesel trucks, RVs, and competitive racing environments on both dirt and asphalt.
During extensive dyno and track testing, Pro Series mufflers consistently delivered horsepower levels equal to or exceeding open pipe systems, while significantly reducing exhaust noise throughout the RPM range. This makes the Pro Series an ideal choice for high horsepower applications where performance is critical but sound control is still required.
Built with a durable fully welded 16-gauge stainless steel case and 409 stainless steel internal construction, this muffler is designed to withstand extreme heat and harsh operating conditions. Featuring a 3.00-inch center inlet and 3.00-inch center outlet with slip-fit connections, it is ideal for custom exhaust installations requiring reliable flow and durability.
