I have two Beagle stainless steel exhaust pipes for sale I used my old one as a patters high quality stainless steel. They are a bit longer at each end to allow for fitting if you have a non standard silencer.£45 each for club members I have them on Ebay for much more. It is very expensive to get pipes bent unless you order in bulk hence the price. The are 22mm diameter 1.5mm thick same as original.
Did you ever sell these pipes Robbie?
