Chris,
Yes, I have wrapped the entire manifold and muffler. It is an effort (did
mine with manifold off the car) but I think it is helping to keep things
cooler. The muffler bracket did cut the wrap and I had to put another
stainless steel strap on either side of the muffler bracket to keep it from
unwrapping. Get the already black color if you want it to disappear w/o
having to paint it, an additional expense. Rust is not a issue here in CA so
I don't know about rust issues. 1.9 Engine does seem a little more gutsy,
but it's so powerful already it's hard to tell! <;)

My goal at the time was to see if I could get the AC to stay cold when the
outside temps reached the mid 90's, but not sure if it worked. I did put a
big water pipe insulation on the return (low pressure) side of the AC hoses
from the chassis to the firewall (next to the transmission) and that seemed
to help quite a bit. Stayed cool over the 4th and the outside temps were
105+. My '84 AC did not come from the VW factory, but is original Westfalia
equipment. I would like to cover the rest of the AC return hose up to the
compressor but am a little chicken that some unexpected side effect will
bite me.

Good Luck,
Steven
