I have just bought a 2012 T100. I've fitted dunstall pea shooters with no other mods. When I removed the standard pipes, I could see they had been taken off before as they had some traces of white heat proof silicon which didn't look very "factory " The bike seems to run perfectly well with the dunstall pipes and the headers are definitely less blue.. Question is. 1, how can I tell whether The bike has had the Triumph Tors programme to allow for decat pipes previously? Hopefully without dealer expense
