I have heard of some people taking out the silencer box in between the maf and the TB. I want to take it out because it seems like it ristrics air flow. What do you do to the hose that comes out from the bottom of the box. I know that the valve cover has a ventilation hose that goes in from the intake and that you could put a little filter on it. Could I just put a filter on the valve cover that way I just get rid of the silencer box that way i could connect the hose from the silencer box to where the valve cover hose use to be. If anybody has sugestions just tell me. thanks!
