I am thinking about either going with a Greddy EvO2 Exhaust system or lowering the car with Tokico D- Specs and 350Z H-Tech Springs

Which would you guys do first, I plan on going with 20's later but the stock 19's work well for right now so figured wheels can wait until last.

 

I'd go with the suspension and handling. But I don't know if it'll be better than stock beside the fact that you'll have a nicer look when dropped.

 

definitely suspension first, it gives the car a completely new look.

 

Get a radar.. It will save you a lot of $$. After that i would go with rims.

 

I do have a passport 8500

 

You have lots of options....I'd go with the cat-back.
Since you already have the Z-Tube to complete the
mod I'd also add the Stillen Intake which contains
a big K&N filter. This completes the cycle, air in
exhaust out and "Sweet" with the cat-back! Lowering
your G will cost you lotsa $. With springs and all
the other stuff to bring it back to factory settings I
estimated my cost would be in excess of $2500.

 

its really up to you, the G already has a sweet sounding exhaust on it, so take it from there

 

Okay so it sounds sweet... You still need to get air out of your car.
My Injen SES pushes out a lot of air, you can really feel the difference.
^ And the SES sounds SOOOO freaking hot
Any breathing mods put together makes a very noticeable difference.
So take a pick or use the ones you find the best deal on
Headers
Intake
Plenum
Cats
Catback exhaust

(im sellin headers for 270! Topspeed)

 

both my cars, my first modification was tints

 

I already put LIMO on

 

oh ok, and you did clear corners i see, maybe you should think of a lip spoiler or something, i just got one on and got millions of compliments about it, I LOVE IT! gives the car a much more aggressive look. I have pictures.

 

i would go with the drop first...

 

i would go this route, cat back exhaust, cats, headers, coilovers, wheels, which is what i plan on doing after i get my HKS on.
