3 Way Valve for Exhaust System

I am trying to find a vendor that can supply a 3-Way valve to switch from a under car exhaust to a side exhaust on a C2 Corvette.

Several folks on the forum advised me to contact Summit Racing, but Summit offers diverter valves and I would need to install 2 separate valves off of each manifold down pipe and I am fearful of too many valves and the ramification of a valve failure.

I was hoping that maybe someone has knowledge of a vendor who sells a 3 way valve (one inlet with the ability to direct the output to either the side exhaust or the rear exhaust) that has a 12 volt solenoid. A 3way valve would limit the installation to two valves.

Am I asking for something that does not exist?

Thanks in advance for your responses---Mark

Call Summit and ask if such a thing exists. If they don't know, ask for the phone number of the vendor and call them.

H'mmm maybe I am confused here but all I have ever known about is a diverter valve that has an inlet and a gate that directs the exhaust to either the exhaust or the side pipe..we called them cutouts that cut out the flow to the exhaust and diverted it to an outside pipe..

In any case I can only see two one on each side if you have a dual exhaust system..We have had them for years and the old ones used a cable like a lawnmower throttle cable to operate..

Is this something like you are are looking for???

I have tried most all of it and now do what is known to work..

I think you are over thinking your exhauast system. Use a single type valve as shown in the previous thread. Place the valve in your pipe to the side exhaust. When the cutout is opened the exhaust will take the easiest way through your side pipes as they are less constrictive and go through your stock system when it is closed.

Thanks for your input. I probably am "over engineering" this project and will try the single valve on each exhaust pipe.
