An added comment. According to some of the blokes standing around on
the jetty you are not supposed to use stainless to make exhaust parts.
NOT NEVER!

If they know so much, why are they standing around on the jetty?

I've seen plenty of stainless exhaust componenents put in the million dollar
plus boats I design. Never heard of a problem. The "make exhaust parts"
part might be relevant because the parts I'm familiar with were bolted
together from pieces fabricated by people who make exhaust their business.
