Hi mate. Congrats on the bike! Glad you're loving it
I don't know about those particular pipes, but there are bound to be people here who will. Are you finding the TORs too quiet?
As for Jenks Bolts, Peter Jenks uses the Delphi New Bonneville forum and posts there quite a bit. Alternatively, drop him an e-mail. I think the ARK is just delayed. They still have it on the site, but there's no price for it yet.
