I was hoping you wouldn't see this, but now that the cat is out of the
bag............
You can see the need for some shielding between the headers and any items
that you don't want at the same temperature. Radiant energy is line of sight. If
the header can see it, up goes the temperature.
Pieces of .015" stainless stood off the header about 1/2" to 3/4" breaks
the line of sight. Building such on the header reduces the amount of material
involved. It is easier to not heat things up than it is to cool it after you
have. Use 1/4" hose clamps to hold onto the shielding.
A small blast tube to keep things moving past the headers is helpful.
I can make a picture if you like. Helps keep heat out of the intake system
and thus more power. Very easy. Amazing results.

I had my older son do a tuning run-up,
while I checked out what I could from
the outside. Dusk was setting
in hard, so it wasn't that bright outside.
But, I didn't expect the exhaust
to be glowing so brightly. The entire
exhaust from the collector back
was past cherry red.
Is this normal? I'm beginning to expect that
my AFR gauge is lying to me.
