That also was a large part of the noise from old VWs, even the very first
water-cooled ones. Intake noise can be suprisingly loud, especially if you
have a good muffler on the output end.

Just for grins, I once fitted a small forklift carb to a Ducati 350 at
my Dad's suggestion. As he predicted, off-idle and low throttle response
was fantastic (at great loss to high end). One thing quite surprising
was it would idle very steadily and reliably, slow enough I could hear
the air rushing in through the intake. I'd never heard intake noise
before on a bike.

That combo would light off with one kick, hands off throttle and at once
settle down to a slurp-thump, slurp-thump idle.
