Description
Overview
The Flowmaster Super 40 Series Chambered Muffler delivers the aggressive, deep, and powerful exhaust note enthusiasts crave, backed by the proven engineering that made Flowmaster a household name in performance exhaust. Built around Flowmaster’s exclusive Delta Flow® technology, the Super 40 offers the best of both worlds — a bold street presence and real performance gains, all in a rugged, universal-fit package designed for the street and strip.
This muffler carries the same deep, muscular tone as the Original 40 Series, but its larger case profile and Delta Flow® internals refine the experience by reducing low interior resonance. The result is a strong exterior sound with a cleaner, more controlled character inside the cabin — ideal for drivers who want an unmistakable exhaust note without excessive drone.
Built to Last
Durability is engineered into every seam. The Super 40 is constructed of 16 gauge aluminized steel and fully MIG welded for maximum strength and long service life under demanding conditions. A high-temperature paint finish helps the case stand up to the heat and elements that come with hard use, making this muffler a dependable choice for daily driving and weekend performance alike.
