Chaps - this exhaust came with my bike when I bought it and is offensively loud (Roy on this very forum sorted me out with an Akro and gabro chip - cheers Roy!)- I am not a nun and i dont live in the middle of an old peoples home, never the less it was too loud for me to keep on - sounds like a load of angry wasps riding chainsaws - so fore warned is fore armed if you don't like anyone else or want something light for a track day let me know - I am looking for £50 plus postage which isnt going to be cheap (£20 ? or something like that.)
