Description
Overview
The Flowmaster Flow FX Exhaust Muffler is built for the enthusiast who wants an economically priced performance muffler without sacrificing tone or durability. Part of Flowmaster’s Flow FX series, this muffler delivers a moderate sound level and refined tone both inside and outside the vehicle, making it a smart upgrade for anyone building a late model muscle car exhaust system. If you’re ready to shop for exhaust that balances value, sound, and build quality, the Flow FX Muffler is a compelling place to start.
Unlike the classic “chambered” sound that Flowmaster has become famous for, this muffler uses a large straight-through smooth core to produce a distinctly different, cleaner note. That straight-through design is what separates this Flowmaster muffler from more aggressive alternatives, giving your car exhaust a moderate character that’s comfortable at cruise yet still assertive under throttle.
Key Benefits
Durability is central to the Flow FX design. Each unit features a fully welded 409S stainless steel case for increased resistance to the heat, moisture, and road abuse that any performance exhaust endures. The compact 4.00 inch diameter round body is engineered to tuck neatly into tight chassis spaces, so it fits nicely on just about any application — an ideal trait when you’re piecing together a mufflers upgrade or a full exhaust system.

Please note that exhaust tips are sold separately, so you can pair the muffler with the tip style that matches your build.
