Hi there- I've a set of RH pipes,unused,for sale,price £ 250 (approx. half price). located in Bristol,or could post. With these pipes you need to incorporate an O2 bung in the rear cylinder header. I can advise on method I used on another set which didn't involve welding,if it helps.Oh,and because the baffles are removable,shortening them (as I've also done on another set) is a doddle.Anyway.Chew it over.
