People have said that as with all else, these stainless 'performance' cans are obtainable and cheap in China, about $30 or less - yet I can't find a decent length one for the 200cc bikes on Ebay Aus. A few monkey bike shorties is all. And Forchetto's Xian mate who used to do them ex UK got a bad rep and has disappeared.
So come on, lets have one of you expats setup an Ebay site for all these cheap parts and accessories like these cans and barkbusters.
And if you are too busy or too lazy, get the wife onto it!
