Flowmasters
This is the reason I went with them. Trying to get a bit heavier sound.
Flowmaster’s NEW Super 44™ muffler with its 4” x 9.75” x 13” all black finish case offers distinct advantages over our original 40 Series™ muffler. Using the technology seen in our 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 we’ve ever built!
