Anyone using exhaust heat rather than water heat on an Edmunds 2x1 intake for the 235? I am thinking about heating it with exhaust heat because it's faster and I think it will make a cleaner looking engine compartment. I was also going to use copper pipe to tap into the headers. Can I use silver solder or is the exhaust too hot? Is this a crazy idea? Am I missing some obvious snafu's? Thanks, Bob
