For the last 4 years I have owned a mustang cobra. So I am used to supercharging not turbos. I just bought an 08' wrx, so please bare with me if I do not understand everything. I already have a perrin 100% BPV. I know it was half a waste of money unless i plan to go crazy with boost, but metal always seems better to me than plastic!Notfunny!. I just wanted to make sure that the list of mods I want to do won't do anything too crazy. I want to put a cobb d/p with perrin cat back(have to wait 3-4weeks for the sedan, or so the sales rep told me). I want to tune with the Cobb Ap and stage two map. Possibly a Agency power short ram, but not positive on that one yet. Should this all be ok for now? I dont want to do anything too crazy because it is my everyday car. Thanks.
