full bolt ons?
hey guys i am somewhat new to tunning and i am trying to figure out what would be full bolt on parts for a 370z. I have stillen intake and berk exhaust. I bought the car used and i am not sure if it has high flow cats, but what other bolt on mods can be done to the car. i thought only headers a pulley and a tune was left, but i have see people talking about Y pipes and x pipes, so i am trying to figure out what is what. thanks in advance guys
