Hello everyone, just after some advice about my exhaust, I think the baffles may need to be replaced as bike sounds different to other models the same as mine, also when I have the silencer off the bike I could here something rattling inside when I shook it, was just wondering how you replaced them, mine has a club foot silencer on if that's any help? Thanks chaps

hello the exhaust needs to be cut open on the down section there's a perforated tube inside with fibreglass packing around it both can be replaced. the club foot dose not need repacking i would just flush it out with caustic soda. i got mine done for me dose make the bike run alot better and is not as loud.

There is a plate in the rear of the silencer part of the front pipe which holds the perforated tube in place. This plate sits just where the flat part of the pipe ends and it gets smaller on the left of Bodwheel`s photo above. You will have to cut the pipe open to weld this back in place. While it is open you should clean everything out and repack it. The clubfoot ends also have packing in them where the end starts before the back box inside the flat part of them. You can just drill some holes around the end of large part of the shot above and use some self tapping screws but cutting it open and welding it is better.
