There you go then. An easy fix for the induction roar. Plus, your ears will thank you for it in the long run!

RE the turbulance and buffeting - have a read of this (quite long) thread, if you haven't already...

Block off your AIS pipe, when the AIS valve opens you get a pulsing noise from the exhaust system into the air box.

You cannot really have your cake and eat it, as they say. More induction noise comes when the engine breathes better. Enjoy the increased performance!!!!
