I wanted a set up where I could also have variable exhaust pressure. I
wanted to race in a club but the car must have a certain dB range at 4500
rpm. My idea was to have an electronically controlled variable pressure
exhaust. at 4500 rpm an rpm switch would switch on a solenoid which would
reroute the exhaust. Like a lawyer you have to find loop holes.
