Thanks for the reply mate -I'm beginning to think you're right - I'll probably keep the bike forever now so would be nice to have the exhaust looking as good as it can be. I'll keep going a bit more with the wet and dry to get it as smooth as possible. Check out the photo of the castle nut, some of the turrets are bit bent too so might take the hacksaw to it. Looks like you can still get replacements for these easily, unlike the silencers..!
