Description
Overview
The Flowmaster Super 44 Series muffler brings serious attitude to your car exhaust with a rich, powerful tone that stands out from the crowd. Built on Flowmaster’s proven Delta Flow® technology — the same design found in the larger Super 40 mufflers — this Super 44 is described by Flowmaster as the most aggressive, highest performing street muffler they’ve ever built in a four inch case. If you’re ready to shop for exhaust that delivers real presence, this magnaflow-caliber-competitor from Flowmaster is engineered to perform.
Engineered for late model muscle car applications, this performance exhaust muffler is a universal-fit component, giving builders and enthusiasts the flexibility to integrate it into a custom exhaust system or a fabricated cat back exhaust system. With a compact 9.50″ body width and a 2.25″ inlet diameter, the Super 44 packs its aggressive sound level into a manageable four inch case that fits a wide range of exhaust automobile builds.
Built to Last
Durability is core to the Super 44’s design. Each muffler is constructed of 16 gauge 409S stainless steel and fully MIG welded for maximum strength and long service life, then protected with a high-temperature paint finish to withstand the heat generated by a hard-working exhaust system. Whether you’re running one of these mufflers on a street car or building a dual setup, the construction is made to handle the demands of a performance exhaust environment.
