Thanks for the information, that's a lot of science I've never thought about before.

Looking at the different exhaust gaskets, and if the whole system will have to come off, it looks like I'll need 3 gaskets(?). 2 minimum if just the front pipe will come off. The big "exhaust silencer gasket seal" that I've discovered on ebay has introduced more headache with finding out which parts I need.
