This is the kind of thing I was refering to. The exhaust temp can be very 
VERY hot . It may be as high as 1800f. I have seen manifolds glowing red 
and I would not want a flamable liquid being squirted on or near it. 
Just a concern. With "regular" anti freeze-coolant do you have temp 
problems???
