We've got the same problem with the Akrapovic full system we got for our curvy. The can is defo Ti, but the downpipes are so light and don't polish up at all. No matter how hard Lissa has tried. Our mate who runs a bike service shop reckons it is Ti. It's going to be going on ebay soon and don't want to wrongly advertise it.
The cans on the Duke are Ti too. Again we weren't sure. Seller didn't advertise them as such, but the insurance quote called them Ti and everybody who has seen em says the same. Confusing or what?
