All the power and performance of Flowmaster’s muscular mufflers without the roaring interior resonance—that’s the idea behind their 40 Series Delta Flow Muffler. It’s the ideal pick for late-model performance cars that want powerful exterior tone while enjoying a quieter ride.

At the heart of the 2-chamber design is Flowmaster’s exclusive Delta Flow technology. This innovative engineering utilizes precision-placed deflectors that not only mute interior sound, they fuel increased exhaust scavenging for the most possible power.

Also ideal for dual exhaust cruisers, the Flowmaster 40 Series Delta Flow Muffler boasts the quality construction you’d expect from Flowmaster. Each Flowmaster Muffler is built with 16-gauge aluminized steel for corrosion resistance and fully mig-welded for maximum durability. Best yet, your Flowmaster 40 Series Delta Flow Muffler boasts a 3-year warranty.
