Any of you guys experienced the Magnaflow for the 08 STI shreiking at around 4,000 rpm? This belongs to the batch with fitment issues also.

It seems the shreiking sound comes from the wastegate at WOT because when I gradually apply power till redline there is no shreiking sound just the clean Subaru rumble.
