just wanted to know if there any performance upgrades for the Infinity G35 out there..... looking for a cat-back exhaust, and cold air????? Unfortunately it's the tiptronic transmission
get nismo products, don't bother with anything else, just go read the forums on fresh alloy.com and you'll know what iam talking about, if you want mad power greddy and power ent. are coming out with twin turbos so wait a while, but the trick is it voids your warrenty, so ask the dealer about intakes and exhaust my dealer is pretty okay with it but it took some reasoning for them to okay it
