If leaving it on helps with cooler air, better response, then how about he people that are running headers??
<font size="2" face="Verdana, Arial">Actually, I have it on pretty good authority that the stock exhaust manifold is stainless steel. It's not iron by a longshot, and is actually pretty good for an OEM piece.Originally posted by GioDiGreek:
I also know the stock headers are cast iron and "holding" the heat...
<font size="2" face="Verdana, Arial">Now we have entered into another interesting conversation. Starting in 2002, ford stopped putting the insulation/sound blanket on the inside of the hood. Has anyone else running aftermarket headers (shorties)noticed changes in their paint due to heat?Originally posted by BRZX3R:
I run a 4-2-1 header and no underhood insulation on my car, and the result is blistered paint on the hood over the header. I would leave the insulation and the heat sheild on if I were to do it over again.
