Was looking on ebay when I saw this item;-

Couldn't believe he was asking £150 for a single pipe which is showing signs of pitting on the outside so can only imagine what it's like on the inside. It does look like Honda have stopped making them for the time being which is unfortunate as the design is prone to rotting. I bought a set about three years ago from Dave Silver for £85 each plus VAT. Always spray WD40 down the pipes before and after running in the winter months, cant believe the amount of water which sprays out when it's running on cold days.
