 Product Description

ALL NEW DESIGN!

We have upgraded our exhaust valve technology from a membrane bellow style actuator to a piston style actuator.

 

A much simpler design that uses less components and eliminates bellow failure in big bore and turbocharged applications. Our piston mechanism stays lubricated by the engines 2 stroke oil sytem and is actuated by the exhaust pressure from the cylinder. Same design works well with naturally aspirated engines as well. We developed this valve design in the fall of 2010 and tested them on turbo charged, and naturally aspirated engines throughout the season with amazing results.You will love the throttle response gained. You can adjust the opening rpm by changing different thrust springs.

We do stock different spring combinations for finer tuning- Kit # 78SPNG sold separately

This new piston style exhaust valve will adapt to your stock valve blades. We supply a locking clip that locks the two-piece valve assembly together and eliminates the two stock springs. Installation instructions and tool included.
