Carlos from Spain:

Very interesting Grant kiss ... wonder if it will improve the sound as well now that partical filters are mandatory

It may improve the intake sound (relative to the exhaust sound), but unlike the intake trumpets of old, the ITB's will be fed by a large intake plenum (for better torque) which will somewhat mute the potential intake sound...
