Flowmaster 40 Series Delta Flow Mufflers


Flowmaster
Flowmaster 40 Series Delta Flow Mufflers

Product images may differ from actual product appearance.

This two chamber design incorporates Flowmaster patented "Delta Flow" technology. The "Delta" deflectors result in increased scavenging for better performance and reduced interior resonance over the standard 40 series with a nice growl outside the vehicle. Muffler sounds great on late model performance cars with catalytic converters. Constructed of 16 gauge aluminized steel and fully mig-welded for maximum durability.
