Description
Overview
The Flowmaster Super 40 Series Chambered Muffler brings proven race-bred technology to the street and strip. Developed from Flowmaster’s Top Ten race muffler lineup, the Super 40 delivers the aggressive, deep, powerful sound muscle car enthusiasts crave while incorporating the performance-minded engineering that has made Flowmaster a household name in the exhaust world. If you’re chasing serious tone paired with genuine flow, this is a muffler built to perform.
At the heart of the Super 40 is Flowmaster’s Delta Flow® technology, combined with a larger case profile that provides the best of both worlds: strong performance and a commanding exhaust note. That larger case shines especially on forced induction and high-horsepower vehicles, where flow and sound quality matter most. You get the deep, powerful character of the Original 40 Series, but with the added benefits of Delta Flow® performance and reduced interior resonance for a cleaner, more refined drone-free experience in the cabin.
Built to Last
Durability is engineered in from the start. The Super 40 is constructed of 16 gauge 409S stainless steel and fully MIG welded for maximum strength and longevity. It’s finished in high-temperature paint to help it stand up to the heat and demands of an active exhaust system. Whether you’re building a weekend cruiser or a high-output street/strip machine, this muffler is made to hold up.
