Zenlim,
the loudness is exactly the same !
As long as is aftermarket blow-off, the moment u release the accelerator and the throttle body closes, the excess pressure build-up in the air ram will get release through the blow off hence the 'siew..siew..' sound...LoLz.
Original evo is blow-in that's why u hardly hear anything.
Siew..Siew..! :)
