I feel so stupid asking these sorta questions...but, being that I'm new at all this, I want to know everything...#1--What is a wategate, and what does it do, and why do I need one?!?...#2--I've heard some people mention having an open downpipe, and it's supposed to sound pretty cool...what does this mean, and if it's so good, how do ya do it?...Thanks.
