i have a 2008 2.4 cobalt sport auto.. i just purchased a K&N typhoon cold air intake. im new to modding but serious into learning so hopfully with your guys help i can get me ahead. so im thinking im putting out 140ish whp. my ultimate goal is to hit 200. so with your guys help, could you lead me to my goal, with set ups, ideas hints and tips? and obviously trying to keep it as cost effective as possible. so i did some research and maybe my next mod will be zzp header and downpipe and a new exhaust. what you think?
