    The “Hush Power II” mufflers from Flowmaster have the great sound of the 1950s-style mufflers, yet support up to 400 horsepower with ease. Mufflers are manufactured using either T304 or T409 stainless steel and finished in durable black paint prior to shipping. Hush Power II utilize guided sound control for maximum flow. The internal design mimics the gas flow of a jet engine to produce optimal tones at all RPM levels. Available in your choice of 3 inlet/outlet sizes, the mufflers are only 18” long by 5-1/2” wide and 4” tall. Sold each.
