Description: Developed from Flowmasters 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 theyve been precisely placed and welded to exacting specifications. Flowmasters exacting placement technology assures that components are welded in the precise location required for optimal Delta Flow performance.(minimize)
