I just knew that it has all been tackled before so invested a few more seconds on the search criteria:
(remove OR removal) AND exhaust AND (valve OR winter)
and within the first two pages of results I had absolutely everything I needed including a photo of a joint blowing just like mine, what section(s) to buy, an ebay seller, which bolts/nuts are hard to undo, tip for putting rubber hangers on etc. Some of the info goes back several years suggesting that in just a few minutes I have harvested years of other owners' experience.
Excellent. Forums are so much more powerful than a Q&A tool
