Flowmaster 80 Series Mufflers

The 80 Series is designed for applications where the muffler must be mounted transversely (cross-flow) behind the rearend. It provides an aggressive muscle car sound both inside and outside the vehicle. A replacement for early and late model Camaros & Firebirds. 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.
