Description

The Flowmaster Original 40 Series Chambered Muffler is engineered to deliver the legendary aggressive exhaust tone that Flowmaster is known for. Designed for drivers who want a deep, powerful interior resonance and a strong exterior rumble, this muffler is ideal for classic muscle cars, late-model performance vehicles, street rods, trucks, SUVs, and street/strip applications.

Constructed from durable 16-gauge aluminized steel and fully MIG-welded, the 40 Series is built for long-lasting performance in demanding environments. Its chambered internal design improves exhaust scavenging, enhances throttle response, and produces the iconic Flowmaster sound profile.
