I have twin exhausts which I think are a complete system for either a 600 or 750. Although I think the 600 only ever had a single pipe. Don't know if that's any use to you They are not the right ones for my 900 as th fitment is slightly different.
just need a single silencer as i am going to take out internals for a bit more noise so a full system would be no good to me and a shame to split it thanks for the offer
