Product Details

The Flowmaster 40 Series Chambered Muffler is the original Flowmaster performance muffler, known for its bold, aggressive tone. This street/strip exhaust muffler uses a classic two-chamber design. It suits muscle cars, street rods, trucks, off-road builds and custom exhaust projects.

Key Features:

  • Aggressive sound: Delivers the deep, aggressive exhaust tone that made Flowmaster famous, both outside and in the cabin.
  • Chambered design: The two-chamber internal layout improves exhaust flow and reduces back pressure. This can help throttle response, torque and horsepower.
  • No internal packing: There is no packing material to blow out or wear down over time.
  • Durable construction: Made from 16-gauge aluminized steel with fully MIG-welded seams. It is built to handle heat and vibration.
  • Universal-style application: Made for custom and modified exhaust systems. Several inlet and outlet configurations are offered across the line.

Whether you are building a street cruiser, a strip car or an off-road rig, the 40 Series gives you a proven, straightforward way to get a classic Flowmaster sound.
