Description
Overview
The Flowmaster Super 40 Series Chambered Muffler delivers the aggressive, unmistakable Flowmaster attitude with the added refinement of Delta Flow® technology. Built for late model muscle car owners who want serious street presence, the Super 40 combines a larger case profile with proven chambered engineering to give you the best of both worlds: real performance gains and a deep, powerful sound that commands attention.
Compared to the Original 40 Series, the Super 40 pushes the tone even deeper while cutting down on unwanted interior resonance. That means you get the classic, throaty rumble Flowmaster is known for without the constant drone on the highway — a muffler tuned to sound mean when you’re on it and stay livable when you’re just cruising.
Delta Flow® Performance & Sound
At the heart of the Super 40 is Flowmaster’s Delta Flow® technology, engineered to maximize exhaust flow while dialing in a rich, aggressive sound signature. The larger case profile helps scavenge exhaust efficiently for improved performance, all while keeping cabin resonance low. If you want an exhaust note that turns heads and a muffler that works as hard as it sounds, the Super 40 is built to deliver.
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 long service life under demanding conditions. This is a muffler designed to handle the heat, vibration, and road exposure that come with an aggressive performance exhaust setup.
