Muzzy headers are running a bit hot. Although we have not had much trouble ourselves,Muzzy's have contacted us stating that they will be sending a new heat sheild for the front header pipe where it is close to the mag cover,as they have notice some excessive heat in that area. Good pro active stance on their part.
Today my header pipes are being ceramic coated by High Tech Mechanical Coatings here in Nova Scotia. He says he will do an extra step on top of the internal and externally coated ceramic chrome finish...he has another black coating that is for Turbo headers that goes on top of the regular ceramic that offers an additional 10% in heat resistance,so I told him to go ahead. High Tech claim that it has drastically reduced the "foot heat" in stock car racing applications he has been doing. I know the guy very well and trust his judgement.
I know this is a Canadian company,and many of you guys are in the US,but this extra step may be offered in other coating shops as well.
Just a thought. I think this process should drastically reduce the cabin heat for those that have mentioned it.
I also welded in the threaded bung for the Air /fuel ratio guage before the coating gets done.
I'll report on the heat issues after the coating.
