Awesome, thanks for the information guys.

Compared to all photos of Remus & Sebring exhausts I can find, my muflers are only half length, so I'm assuing they have been shortened by the original owner. No baffles at all.

I took the bike for my first decent ride (80km) today and by the end of it my ears were ringing!!
These mufflers will need to be replaced to pass a roadworthy inspection.

Thanks for your help!
Russ.
