Only asking as a RS500 hose reduces to 63mm when going from the cooler to TB (76mm both ends but reduces to 63mm in the middle)

Wasnt that to stop turbo surge or something along those lines. I remeber reading somewhere that the rs500 had something to restrict it to combat surge. Either in the exhaust or as you mention here by going down to 63mm. Then again i could be totally wrong lol
