The Original 40 series muffler delivers an aggressive exterior and interior tone. If you're looking for that original Flowmaster sound this is the muffler is for you. Constructed of 16 gauge aluminized steel and fully MIG welded for maximum durability.

Developed from Flowmaster's line of Delta Force race mufflers, Flowmaster mufflers with Delta Flow technology provide superior scavenging of exhaust gases than a comparable (standard) Flowmaster muffler. The results: increased horsepower, torque and fuel economy, along with reductions in exterior sound levels and interior resonances.

The key to Delta Flow technology is the three deflectors that form the delta shape inside the Power Chamber. These three deflectors function properly only when they've been precisely placed and welded to exacting specifications. Flowmaster's exacting placement technology assures that components are welded in the precise location required for optimal Delta Flow performance.Vehicle Type: Classic Muscle Car
