I'm new to owning a hemi (used to have a 2.7)and I'm trying to learn what I can about it. I have seen a lot of people talking about catch cans, and i started researching. It seems this is a pretty important thing to have, and i want to make sure i get it right when i purchase one. So what do i need to look for when i make the purchase? It seems billet tech is pretty popular. I found one on speedlogix for about 100 bucks and I'm wondering if that would work. Thanks all.
