Hi Grant, Johan says just chop the whole centre out, replace with a single full length perforated pipe, then repack. That's what I'm going to try. Will post some pictures as I go. Interesting thing about these cans, they are all stainless steel and I feel they will take a lot of bashing about. As I fall off fairly regularly that could be an advantage. I'm never going to be a concours guy like you and Robert (NSX) so titanium or carbon cans would be like pearls before swine for me. Like your developments for your upcoming trip, are you taking your girl on pillion?
