Super 44 Series Muffler

The Flowmaster Super 44 Series Muffler (SKU FLO943045) is a direct-fit aftermarket exhaust component engineered for drivers seeking balanced performance without extreme volume. Built for muscle cars, trucks, and street machines where quiet operation matters as much as presence, the Super 44 delivers a refined, aggressive note while maintaining highway civility. This muffler suits enthusiasts who reject both stock whisper-quiet exhausts and race-only designs—it's the engineer's compromise between stealth and attitude.

The Super 44 Series features a robust 13 x 9.75 x 4 inch oval steel body with 3-inch center inlet and outlet ports, optimized for minimal backpressure while controlling resonance across the RPM band. Weighing 10.4 lbs, the welded steel construction is finished in durable black paint to resist corrosion and heat discoloration. The 19-inch length and compact profile allow straightforward installation on vehicles with limited underbody clearance, and the center-in, center-out configuration keeps exhaust flow straight and efficient—no restrictive bends or internal turbulence that chokes horsepower.

Mechanics and tuners specify the Super 44 Series for late-model domestics, imports, and modified platforms where OEM muffler swap is the quickest path to a quality tone signature. The 3-inch diameter ports work well with headers, mid-pipes, and cat-back systems from 250 to 450+ horsepower. Mounting is bolt-on with standard clamp hardware; ensure your vehicle's exhaust hangers are in good condition and aligned before installation to avoid vibration and premature separation.
