In regards to tha waste gate all turbo's are fitted with a waste gate this is a fail safe measure for when you back off tha throttle & tha butterfly in ya throttle body shut's all that boost needs to go somewhere this is why a waste gate is implemented they are generally rather quiet but a blow-off valve is tha one that makes tha big noise normally 95db is tha legall limit for them once it's sound goes higher than 95db this is considered noise pollution this is tha same for car sterios and exhaust noise
