About the Flowmaster Super 40 Series

Flowmaster’s Super 40 Series is a high-performance chambered muffler designed to produce a deep, aggressive exhaust note while supporting vehicles with substantial horsepower. Flowmaster uses race-proven Delta Flow technology in the series and specifically identifies it as an excellent performer on high-horsepower applications. The result is a strong exterior sound with the distinctive low-frequency character many enthusiasts associate with Flowmaster. Most Super 40 configurations are also listed with noticeable interior resonance, so the series is best suited to drivers who want an audible performance exhaust experience rather than a near-stock cabin. The larger case compared with some of Flowmaster’s more compact aggressive mufflers helps shape the tone while still fitting a wide range of muscle cars, trucks, hot rods, and custom exhaust systems. The lineup includes multiple center, offset, dual-inlet, and dual-outlet combinations, giving fabricators flexibility when matching existing exhaust routing. Depending on the part number, construction is available in aluminized steel or 409 stainless steel, with fully welded cases designed for durability. The Super 40 sits on the aggressive side of Flowmaster’s street muffler range and is a strong choice for engines that need both exhaust capacity and a prominent sound. For a powerful street or performance build, it offers the deep tone, durability, and Flowmaster chambered character the series is known for.
