Street Chambered Mufflers

Flowmaster® manufactures a wide variety of Street Mufflers that covers numerous applications and sound level choices allowing you to custom tune the sound of your vehicles to exactly what you want, both inside and outside the vehicle. We have mufflers designed for anything with an engine from large displacement big block engines to small four cylinder engines and everything in between.

Delta Flow technology provides superior scavenging of exhaust gases. This results in increased horsepower, torque, and fuel economy while reducing exterior sound levels and interior resonance. The deflectorsfunction properly only when they have been precisely placed and welded to exact specifications. Only Flowmaster’s state-of-the-art electronic sensing equipment places components to a tolerance of +/- .004”, the tightest specifications in the industry.
