My current mods are... Air box mod, straight pipe taking place of resonator, and new performance muffler. I plan on doing the stage 2 kit and header downpipe combo, what brand should i use for header and downpipe?? Also i plan on leaving my car alone after that is taken care of (performance wise). Anything else you would think i should do to keep my car running good and safe? Thanks for your help guys

Anyone?
