Description

The Flowmaster Super 50 Series muffler is a larger version of the 50 Series Delta Flow muffler, originally designed for trucks and SUVs but also suitable for muscle car and high-performance applications. This chambered muffler is constructed from 16-gauge aluminized steel with fully MIG-welded seams for maximum durability, and finished in high-temperature black paint. Featuring a mild to stock exterior exhaust tone, the Super 50 Series aims to reduce interior resonance while providing improvements in horsepower, torque, and engine efficiency. Its larger case size makes it an excellent choice for large displacement vehicles. This is a universal muffler and some adaptation may be required for installation. It is not reversible and does not come with hangers, clamps, or exhaust tips, which are sold separately. The muffler has a 3.00-inch center inlet and a 3.00-inch center outlet, with an oval shape and dimensions of 5.00 inches in height, 10.00 inches in width, and 17.00 inches in body length, for an overall length of 23.00 inches.
