Alright! Now that most of my debts have been settled, I can start looking forward to making the G mine...

Stillen cone intake & z-tube(installed) http://www.amazon.com/s/ref=nb_sb_ss_i_ ... Caps%2C232
Motordyme 5/16 spacer(waiting for warmer weather or til I break down and get my Mechanic to install)
ClutchMasters Stage 1 clutch with stock flywheel http://www.andysautosport.com/infiniti/ ... 42590.html

I have done some research but have not seen many options for cat-back exhausts for sedans.
There's the MagnaFlow kit: http://www.autozone.com/autozone/parts/ ... 715_0_4299
and a kit from Borla: http://www.amazon.com/Borla-140093-Cat- ... xhaust+g35
Has anyone installed either of these kits or heard anything about them? Or any suggestions? I just want a kit that will improve performance while keeping the original tone/character of the car once I get the UpRev tune. Speaking of which, What does the UpRev tune do exactly? Is it just a recommended brand ECU tune for G35s, or does it reprogram the ECU and raise the rev-limiter?

I would only do the tune after you have some intake/exhaust mods. You're on the right track!

For sedan exhaust give Mike a yell at tunerzstore.com. He has a modded '04 and will know the options.

Get most of your upgrades done first before tuning. It gets expensive to do a tune everytime you get a new upgrade.

Hell, I'll never get a custom tune at this point. I won't have the car more than another year so it's simply not worth the expense to me at this point.

I installed a Stillen catback exhaust and intake w/ Z-tube a few years ago on my 04 sport MT sedan and love them both. They seem to complement each other. I noticed a big difference after installing the intake. Exhaust had been in place for three months. Wifey says exhaust is too loud, so I know its good! Here's a quick youtube vid of exhaust and intake sounds for your listening pleasure. I have to admit that the Stillen exhaust does drone a bit at 70-75 mph, so I just cruise a little faster. I was thinking about the Hypertech programmer (10-12 bhp, IIRC). It has a map for the Stillen intake. Any thoughts out there?

Nice sound, that ride belongs to another member here on the site.

Finally had good weather on a day off last week, so I got the spacer installed. What a huge difference! You can feel the few extra horses, but how much easier the engine breathes really helps. That and a clean filter. Can't wait to figure out my next move(financially). Might be moving up to Mass. this year, and well, RWD+ snow won't cut it. So I will have to either find a little 4x4/FWD klunker for the winter or trade for a G35x. I'd hate to loose my G.

For snow it's not necessarily about 4 wheel drive, but more about your tires and the ability of the driver. There are lots and lots of 4 wheel drive cars stuffed into snow banks every winter.

trust me I know, lived up in mass for 24 years. Seen my fair share of morons blow past me in audis or big 4x4s because I'm taking it easy on snow-covered back roads... Only to find 'em spun out or in the woods a few turns further. HOWEVER I can say after a visit home in January plus the 'mild' winter in NC, I'll want another car for when the roads get slick. I could live with just my G, but i'd run the risk of getting stuck. Don't get me wrong, I know my limits, and have spent a few afternoons in empty parking lots learning them. I also know when to just stay home. But the biggest reason I want a second car is to minimize the chance of loosing my 'G because someone else can't use common sense in the snow.

Good reason and, if you plan to keep the G for awhile, a second reason would be to keep all the salt and crap off it.

Another popular bolt on option for the 03-05 sedan is to replace the stock mid pipe with a stock mid pipe from a G35 coupe or an FX35. Saves a lot of weight and sounds better. You can get the coupe mid pipe for around $100.

yea I heard about that so I might end up doing that if I decide not to upgrade...
