I bought my 05 WRX back in early January. I finally saved up enough money to start modding the car. Right now the car is entirely stock other than being lowered 1.5inches. I was just wondering what should be the first mods I do. I have absolutely no where to start. A couple of my friends who own subies say to start with an Up pipe/Down pipe but I'm not to sure what to do so I'm here to ask you all: What should be my first mods?
