Super 10 Muffler 3in Off set In 3in Center Out

The Super 10 Muffler 3in Offset In 3in Center Out from FLOWMASTER delivers the aggressive sound and performance exhaust tuning that serious mechanics and hot rod enthusiasts demand. Designed for builders who want to maximize scavenging efficiency while maintaining a factory-style exit profile, this muffler bridges the gap between weekend warrior builds and street-legal performance applications.

The offset inlet with center outlet configuration provides flexibility in exhaust routing without sacrificing back-pressure management or sound quality. FLOWMASTER's Super 10 series uses a tuned chamber design that reduces interior resonance frequencies responsible for drone at highway speeds while enhancing scavenging—the critical process where exhaust pulse dynamics pull fresh charge into the cylinder on the next intake cycle. Constructed from mandrel-bent steel tubing and welded internals, this muffler weighs 6.45 pounds and measures 10 x 4.5 x 14 inches, making it compact enough for tight engine bays yet substantial enough to handle high-temperature exhaust flow without thermal degradation or structural failure.

This muffler is suitable for carburetor and fuel-injected engines with displacements ranging from 283 to 502 cubic inches, making it an excellent choice for both classic car restorations and modern muscle car upgrades. The 3-inch offset inlet accommodates various exhaust piping configurations, while the 3-inch center outlet allows for clean, underslung tailpipe routing, ensuring compatibility with a wide range of vehicle setups.
