OK, I have a question, I asked an IA friend and I'm not sure I agree with his
answer so I'll ask the group. My neighbor is a round track guy and he has his
headers wrapped with fiberglass insulating tape, he says this will keep exhaust
gas hotter and therefore less dense. Exhaust gas that is less dense will exit
without as much friction in the exhaust system, hence less back pressure. Ok,
the IA says by keeping the heat in the exhaust system the S.S. steel exhaust
pipes will be more prone to cracks because of excess heat. If one had a mild
steel exhaust system then it wouldnt be as much of an issue, but if on the
other hand one had stainless??? The question is, " To wrap or not to wrap THAT
is the question. Are there other issues with having higher pipe temps, would
this cause higher CHT or even higher exh valve temps? Comments?
