^^ so why exactly are you so set on it?
do you need it for:
- loudness? (it will accomplish, the car will be obnoxious to drive tho)
- geek factor? (it will do, i know as i am a geek ;)
- performance? (will have to retune for much more freer flowing exhaust whenever the valve is open, otherwise you get lean condition at high rpm - so need to have two tunes for when it's opened and closed. Also as was already mentioned it will take away from low-mid end torque as there would be close to no scavenging for those frequencies)
this solution would be much better suited for a turbocharged car
much better solution is this IMO:
