if you are on a budget or even if you arent, The stock YZ pipe with help your bike to run like it was made to. A free performance modification is to move the exhaust cam on tooth on your bike to match the valve timing of the YZ
I will look to see if I have a 426 exhaust, Im pretty sure I only have one from the YZ450

Thanks for the reply - I managed to find a used Bills Pipes Thunder Series tailpipe in the UK for £100. I know it sounds like a lot of cash but they are quite hard to come by in the UK (my experience anyway !!). Picked it up today and fitted it this afternoon - awesome sound !!
I plan to do the exhaust cam mod next - just want to get used to the power delivery 'before' .... so that I can tell how much different it is 'after' :smirk:
