Waste gate is completely different to a dump valve, wastegate regulates boost pressure and is usually found in the turbine housing on a turbo. A dump valve is on the boost pipework between the compressor outlet and throttle body, usually found on the intercooler on subarus.
Its a dumpvalve you want for the noise is it?
