arospeed exhausts control valve

Arospeed Exhaust Control Valve was created as an alternative to the standard silencer typically fitted in the tip of performance exhaust systems to lower the sound output and maintain some back pressure in low range RPM. The Arospeed Exhaust Control Valve is a spring loaded butterfly valve that can be installed to the main piping of an existing exhaust system. The angle of the valve can be modified on the fly from within the cockpit to provide complete control over exhaust decibel output.
