i have a 1990 mx-6 gt 5spd. all i do is drive back and forth to work but i want the blow off sound when i let off the gas. it very faintly whistles when i get on it but i cant hear it blow off when i shift or let out of the throttle. i have no clue about turbos and no im not in it for power just the sound. dont want it idling rough or sounding ghetto. if i need to buy anything where and what do i need thanks.
