just wondering over here from 3GWRX. i'm pretty active over there, but i like to branch out and i don't like to go to NAZIoc, so i figured i'd give this place a try. i drive an 09 wrx with an AP Perrin stage 2 map, Perrin catted DP, and AVO panel filter. still hitting 17+ psi with the stock catback. stealthback=holy **** did i just get whooped on by a vacuum cleaner?
really crappy pics of my car:
