Zoomers Cyclone muffler design allows for an efficient flow-through muffler. As the turbulent exhaust gases and water enters the chamber's larger diameter, it is contoured and spun by it's patent protected stationary vaines. The result is a drop in pressure, which scavenges the water and gas. This scavenging effect allows your engine to breathe better resulting in increased performance.

Zoomers look great has anyone done db level tests on Mercury 500 efi and if so what were the db levels ?
I would gladly spend $1400 to pass noise test but wouldn't be real happy if they can't pass.

How safe are they to use with out the set screw. Not crazy about the idea of putting a hole in the exhaust pipes, because it will look bad when not running the mufflers?
