Most of these aren't worth using. There's really no need to go through the effort of taking the cooler off and using some other type of set up. Just leave the cooler on it. Have the (exhaust gas) ends welded shut if your worried about it leaking internally.

Eliminating things on the engine that are legally required to be there is a mistake. Your opening yourself up to problems from a very simple visual inspection by the wrong person. I know they don't happen often in most places but why take an un needed risk?
