ok guys im new to the world of the infiniti im planning on getting a g35 coupe im going straight performance first. what would be a good step by step performance upgrade? like im pretty sure cold air intake and exhaust, but after that im lost and i dont want to screw up the motor by throwing on a mod that needs a prior mod to work correctly

^ search.
Stillen ztube, motordyne 5/16" plenum spacer, full exhaust, if it doesn't come with Y pipe get 350 HR Y pipe, High Flow cats or motordyne ART pipes, and valve body upgrade if you get automatic. And then a tune

lol thanks but still a newb. i dont quite know what any of those parts are

that's what google and the search function is for

ok thanks where should i get the motordyne spacer?

^ ebay, type Motordyne 5/16" plenum spacer. If you live in a warm climate get the basic spacer, if winter's cold where you live get the cooper iso thermal

lol found the copper iso for $225 i cant find any of the exhausts tho i got a pretty high budget but if i can save a little on a few things it will be more money for other things

lol i think the dual cat backs. im into diesel trucks if im not mistaken thats pretty much straight piped? will it be loud?

hks is one of the loudest ones. Especially if you replace your cats too

ok im lost now i thought that was full exhaust the one on ebay

the one on ebay is a HKS replica if i'm not mistaken, it replaces the mufflers, the midpipe and the Y pipe. Not the catalyc converters. The cats are behind the Y pipe

yeah smoke im right with you i just traded my supra for a g35 and im lost on this car....i have been lookin at the motordyne 5/16" iso, and i have to save a get a exhaust....but after that i dont really know what else to do, even tho im wanting to put a greddy twin turbo kit in it later on

Year of car? 5AT or 6MT? Any current mods?

its a 2003 6spd...no current mods
