Super 40 Series Muffler

The Flowmaster Super 40 Series chambered muffler is engineered to deliver an aggressive exhaust note and enhance performance, particularly in high-horsepower applications. It incorporates Flowmaster's Delta Flow technology, designed to provide the deep, powerful sound characteristic of the Original 40 series while minimizing interior resonance through its larger case profile. Constructed from durable 16-gauge aluminized steel and fully MIG-welded, this muffler is built for longevity. Its black, high-temperature paint finish adds to its robust construction. The inlet and outlet connections are 2.50 inches with slip-fit and clamp-on inlet types, and a center outlet location. The oval body measures 5.00 inches in height, 10.00 inches in width, and 13.50 inches in length, with an overall length of 19.50 inches. While it is legal for sale or use on Emissions Controlled Vehicles, Uncontrolled Vehicles, and Racing Use Only Vehicles as it does not affect emissions, it is important to note that some parts are not legal for use in California or other states with similar regulations. Hangers and clamps are not included and must be purchased separately. The manufacturer suggests compatible pre-bent tailpipes for various classic Chevrolet, Pontiac, GMC, and Mopar models, noting specific exclusions such as 'Does Not fit Wagons' for certain Chevrolet applications.
