First commute into work this morning with the filters on and noise off the engine during acceleration and engine braking is being amplified by the airbox as its more open. Its got that plastic type booming noise , if that makes sense.

Not sure if I'll get used to it as it sounds unpleasant. Is it possible to line the air box to deaden this sound. Apologies if that's a daft question ;-)

Bike feels great though.
