STREET CHAMBERED MUFFLERS

The muffler design that we’re known for! Flowmaster Street Chambered mufflers have chambers and angled deflectors that manipulate sound frequencies while accelerating the exhaust pulse. Giving your hot rod a raspy, throaty tone. The newer designed “Super” mufflers have a deeper tone and less interior drone that older designs.

FLOW FX MUFFLERS

Flow FX mufflers are perfect for the person looking for an aggressive exterior and interior sound level with all of the performance benefits that you would expect from Flowmaster. New features include bright 409S stainless steel tubing mated to our new Flow FX straight-through mufflers with a large 3.00 inch core for maximum performance and a deep, aggressive sound. Manufactured in the USA and is covered by Flowmaster’s 1 year warranty.

LAMINAR FLOW MUFFLERS

This is our newest muffler technology. Apposing perforated cones direct sound frequencies into themselves for sound cancelation, like our chambered mufflers, but the addition of a thermal blanket inside the muffler helps accelerate the exhaust pulse by keeping the heat energy inside the muffler. This also results in a more classic “glasspack” type of tone from the muffler.

RACE MUFFLERS

Flowmaster utilizes multiple muffler designs to help control the sound level of different types of race vehicles around the world. These mufflers provide maximum scavenging for added torque and horsepower for all kinds of race applications. Our revolutionary technologies allow Flowmaster to shrink case sizes for improved ground clearance, while at the same time reducing exterior sound levels and interior resonance, major causes of driver fatigue. Whether it’s our Delta Flow®, Laminar Flow, or Reflection technology, Flowmaster has the muffler to help keep your race vehicle where it belongs, on the track.
