Im a little confused on what kind of mid section exhaust and headers to buy. ive searched and cant find what im looking for. First off will 350z headers fit a G35. i've seen application for 350z and not g35 so i didnt know if they were different. I know the mid section is smaller for the 350z than g35 but will it turn on a CEL if i get catless because no one seems to make high flow cat mid sections? and do headers depend on MT or AT? thanks guys it just gets confusing looking at websites when they only list certain things.. anyones advise would be great
