Anyone install one of these on a WRX? The benefit seems great for the price... I know its pretty common to do, and I've looked at some tuturials/how-to's on Nasioc so it doesnt look too hard but would prefer to have help (especially if you have done it before). I can pay you some but not much (however I have a keg of beer always on tap at the house you are welcome to

).
I dont have the parts yet, but it seems as though it can all be picked up at a local advance auto parts or autozone...
Also I plan on getting PnP Grimmspeed Headers very soon, anyone help me with those too? (mostly need lift/good jacks and stands)
P.S. I dont want to take it to S&R to get it done, I want to work on it aswell to learn and what not.
