Charlie, I forgot to mention that I have had pipes made by Alldens Exhausts, near Market Raisen, North Lincs., by Custom and Classic Fabrications, very near to where I live, and by Andy Newton of Granfab, which is in the grounds of Strelley Hall, near Nottingham. The ones made by Andy Newton were the best, but he took forever to do them, (over a year !)
