These my first skii, can someone tell me the best temperature that lexhaust must be to perform well? As cold as possible? I can conect it in simple and dual cooling on lexhaust manifold, there are 3 hole ... These the same model as the one on the picture.

Try running the least amount of water into the pipe as you can without it getting too hot. You want to be able to put your hand on it for a couple seconds before it is too hot. I run my coffman around 170F degrees.
