Description
Overview
The Flowmaster Super 40 Series Chambered Muffler brings together aggressive street presence and refined performance in one hard-working package. Built around Flowmaster’s proven Delta Flow® technology, the Super 40 delivers that deep, powerful tone the 40 Series is famous for while adding the flow characteristics and low interior resonance that serious enthusiasts demand. It’s engineered for drivers who want their exhaust to sound as strong as it performs.
Thanks to its larger case profile, the Super 40 offers the best of both worlds: the aggressive, throaty exhaust note of the Original 40 Series paired with the smoother, more controlled performance benefits of Delta Flow®. That means you get a bold sound outside the vehicle without the harsh drone inside the cabin, making it a standout choice for street and strip builds alike.
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, then finished in high-temperature paint to help it stand up to the demanding conditions of an exhaust environment. This is a muffler designed to keep sounding great and performing hard for the long haul.
