Hello everyone

Currently drive a 09 lancer ralliart, can't stand the crappy build quality and such of it and looking to get a g35 that has been a favorite of mine but never got one. Now I'm looking into getting one most likely (small part of me wants a 350z too so either way this info goes to both).

I have been researching across different websites and all to figure out the mods I'd wanna do and just wanted to get confirmation on it.

I plan to buy either an 05 or 06 g35 coupe auto. I'm looking for a white but found a black 05 with 32k miles for 22k. May go with that one but was hoping to get a 06 with projectors. I know its a non-rev.
Mods I plan to do are 5/16 spacer, popcharger/ztube, some kind of full exhaust/test pipe or high flow cats and a tune to top it off.

I'm not going to do it all at once. My plan was to do the spacer and exhaust first with test pipe or do hfc, followed by intake. Lastly the tune. To confirm I could do all those mods and wait for the tune when I decided to with no problems correct? Or would any of those mods require a tune right of way? I researched and think I could get a tune whenever if I'm right.

So does all that sound correct? Would a test pipe be better or do an exhaust with high flow cats?

thanks for the help.

Kevin

p.s. other mods I've planed are new hid bulbs, like 8000k, black aftermarket grille, paint stock rims, debadge entire trunk, and maybe a sub.
