Flowmaster 40 Series Delta Flow Two Chamber Muffler

This two chamber design incorporates Flowmasters 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. Sounds great on late model performance cars with catalytic converters. Constructed of 16 gauge aluminized steel and fully mig-welded for maximum durability. Developed from Flowmaster's line of Delta Force race mufflers, Delta Flow technology provides superior scavenging of exhaust gases even over a comparable (standard) Flowmaster muffler. By using multiple deflectors vs. a single deflector, Delta Flow technology provides a cleaner and faster scavenging path by eliminating the chance of turbulence commonly found behind a single deflector model. These Delta Flow deflectors can only function properly when they've been precisely placed and welded to exact specifications.
