Description
The Flowmaster Super 40 Series Chambered Muffler is engineered from Flowmaster’s Top Ten race muffler lineup and refined for street and strip performance applications. Designed to deliver maximum power and an aggressive exhaust tone, the Super 40 features Flowmaster’s proven Delta Flow technology to enhance exhaust scavenging while minimizing interior resonance.
With its larger case profile, this muffler delivers exceptional sound and performance, making it especially effective for forced induction and high horsepower vehicles. The Super 40 retains the deep, powerful exhaust note of the original 40 Series while providing improved efficiency and reduced drone for street-driven performance builds.
Constructed from heavy-duty 16-gauge 409 stainless steel and fully MIG welded, this muffler is built for durability under extreme heat and performance conditions. Featuring a 3.50 inch offset inlet and 3.50 inch offset outlet with slip-fit connections, it is ideal for custom exhaust systems requiring aggressive sound and reliable performance.
