Do some more research on valvetronic but I remember seeing someone's write up on them. Apparently the fitment was horrendous and the valve stopped working shortly after receiving it. They added a whole bunch of emails to the thread too with valvetronics response and their answers were very sub par. As far as noise, the mperformance is very quiet when driving day to day but considerably louder on start up. The valvetronic is a bit louder than the mperformance with the valve open and about the same volume with the valve closed.
