I have heard there is a way to setup with a switch for a dual tune. one for the ypipe open, and one for the ypipe closed. Is there any information on how this is done without using multiple chips? please explain. ty.

 

Using crome you would probably need something like a Moates 2 timer.

would it really make much of a power difference with the Y-pipe on or off that would necessitate a different tune?
