    Well, block the OE dump valve, and don't put an aftermarket dump valve on, and watch your turbo die in front of you on the M6.

    That isn't dump valve noise, that is wastegate chatter (i.e. what a dump valves try to solve.)

    That flutter sounds nasty. You can get a loud flutter sound thought by using an induction kit along with an aftermarket dv.

    know a few people with external waste gates and they have replaced there turbo often as the bearings and shaft have warped. dont do it, stick with a b.o.v

    although i do like the rally chatter sound. the psssshhhht is enough for me that and the fact i know my turbo is going to last longer.

    from experience the HKS B.O.V is the loudest and best sounding if you like that sort of thing,
    im sticking with my baileys DV26 sounds perfect and is great with the Z20LET
