Guys, I can't think you enough for all this information.
Sounds like the H&B rack is OK, I will check out the Touratech mounting pucks though.
Teflon spray eh? Sounds high-tech... Sucker for high-tech, I'll ask Thorsten about it.
Paul, I had heard something about the Metal Mule exhausts, I'll take a look. It is a large price difference indeed. They don't mention the catalyser... I'll mail them and find out what the deal is with that.
