So I have been searching the crap outta forums and find lots of stuff on old mustangs but not much on the newer ones. I just installed the Paxton and don't really like the hack job of the pcv routing I had to do, and the little ball valves sent to me are kinda a joke on keeping back pressure. Do most of you guys just attach breather filters on the stock valve cover nipples, or are you running catch cans, or like MMR vent can? Just trying to figure out if it is worth keeping the stock PCV system or just throwin a set of filters on there. Thanks guys
