A technical question for Calum Douglas and others. What is the effect of the cold ram air (especially at altitude) on only the lead exhaust pipe and the last being the hottest?
it must work this way, also putting serious thermal stress on the first one or two of exhausts and not helping much with cooling others, the fact is just Germans have used such solution with remaining nation rather avoided fairing around exhaust pipes, i would take a risk with saying that was overengineered solution....
