eat through stainless in a matter of weeks.<<
Didn't know that. More information please, Graham.
In fact Europa strongly recommended lagging. I took their word for it and did
it. I do know the exhaust guys who did the job so I'll ask them about the
possible effects on resonance. Europa did feel that our EGTs were a bit high, on
the other hand they don't fit EGT so high compared to what? I ask myself.
Exhaust valves are Nimonic I think so creep is less of a worry.
