Has anyone out there thought about bypassing the catalytic converter after the car has warmed up. How much power and milage gain would potentially be gained from bypassing it.

I did a quick sketch of possible bypass system with a shutoff valve. It seems to me it would be fairly easy to implement. The operator will be responsible for turning the system ON and OFF
