To cure that annoying tweet: 54mm hole drilled out of exhaust, which removed part of baffle. Bought turn-down exhaust spout and welded into place. All sprayed with BBQ heat resistant paint and voila! Sounds like a proper bike now but by no means is it loud - just a deeper tone.
Used a welded angled outlet spout with a 54mm od tube (18GBP), from PJEngineering in the UK
