Thanks for the feedback and suggestions folks. Much appreciated.

Yeah ... we have to wear helmets here in Singapore. I have two.My'riding' helmet is amodern, sound insulated, Jet-style open face.My 'looks' helmet is aregular,old classic. The pipes are loud with both.

On the modern helmet, with the exhaust roar muted a bit, I canactually detect a 'clicking' deep in my skull which I suspect ismy eardrums popping in tune with the exhaust. Even after a half-hour ride, when I get off, I have noticeable inner-ear ringing. Just like after a loud concert. A mild headache then sets in.At first, I put it down to conincidence. Now, I'm beginning to suspect otherwise.

It's a pity to put in earplugs, thoughI'll certainly give it a go. The old pipes are still at the shop waiting to be picked up. I might leave them there before I decide what to do.
