Super 40

The Super 40 5X10-inch case design, modeled after Flowmasters Top Ten race mufflers, gives you a deeper tone that retains Flowmasters famous 40 Series sound and feel. Flowmasters Super 40 is the most aggressive, deepest sounding street 2-chamber muffler. The classic black case maintains that original Flowmaster look.
