We think exactly alike!

I've had ideas just like that with the exhaust and the intake. But mine differs in that the car will sound and behave stock, but have relays that activate with the VTEC signal from the ECU that opens up electric plates to open up the intake or exhaust. They sell stuff here http://www.quicktimeperformance.com/QTEC/

Good luck and update us. I'm going to do this someday when I have the time and money. Should be easy though.
