Super 44 - Two Chamber Mufflers
Flowmaster’s NEW Super 44 muffler with its 4” x 9.75” x 13” all black finish case offers distinct advantages over the original 40 Series muffler. Using the technology seen in their larger Super 40 mufflers, the Super 44 delivers a rich deep tone, an improved flow path radius, optimum internal flow and sound control, all created with Flowmaster’s Delta Flow technology. It is the most aggressive, deepest sounding, highest performing four inch case street muffler Flowmaster has ever built! Overview
