The plus side of stainless steel,as you know,is the fact that the corrosion problem is pretty much eliminated. However,one of the understated benefits of exhaust coatings is their insulation properties. I'm not saying you have to coat stainless headers. It's not mandatory to do so unlike mild steel headers. However,it does help stainless,too. The 2" stainless steel headers on my ZR-1 were made by Micron in England,who build most of the exhaust systems used in Formula One. They were made of 321 stainless,a very high grade,and cost over $1,200 back in 1998. Not trying to impress anyone but the point I'm trying to make is that the cost to coat them at that time was around $125,inside & out. Pretty cheap for less heat radiation and a few more horsepower. And people wonder why I'm not buying & building ZR-1's anymore. <g> Clint Hooper H&H Custom,owner 1969 El Camino ProTourer 2001 H-D FLHR custom bagger http://dalesplace.com/misc/friends/clint/clint_hooper.htm ----- Original Message ----- From: <[EMAIL PROTECTED]>
It sounded strange to me too that it wouldnt give any gain at all, but maybe its their marketing gimmick. like "stainless headers are is a bit more expensive but you dont need to coat them" André > As a general rule,I never buy headers already coated.
