Even the open side of the Roush muffler is still muffled. It is just straight through the muffler. Which gives a completely different sound than just open exhaust. It just uses an electric valve. When closed, it flows through the mufflers to be quiet. When open, it flows straight through the muffler.
And there is a nice, half price alternative to the Roush, Varex.
