TO THE OP:
Any bolt on mods such as intake, headers or exhaust should help you with some get up and go for a bit. But if you really want to go faster with it I'd say boost it. If you don't want to risk that then just search for Nismo parts. They have good stuff for Nissan cars. Please PM me if you want to know more.
I have been a member at some large Nissan forums for a few years and know most of what is out there for 3rd gen Altima mods. I have a WAI, much like yours, lightweight stock-size crank pulley, grounding kit, front strut tower bar, lowering springs w/ KYB-GR2 shocks and struts, full 2.5" catback, and catless y-pipe. I also have motor mount inserts which have been sitting in my basement for over a year waiting for installation. The rear mount requires dropping the sub-frame which is what also is needed for the front sway bar. I'm hoping to kill two birds with one stone at some point, when I can afford the front and rear sway bars.
I also have a 3" in/out resonator waiting to get installed. I was supposed to get in with a local guy to have the straight section of my exhaust changed to 3", but that didn't work out and looks like it won't happen for a while. I'm waiting for one of my pre-cats to fail so I can get high-flow pre-cats. And when I get the spark plugs done next year, I may get a phenolic spacer kit.
I have no plans for FI though since $10k is too much to be putting into a car for one mod. The gains would be nice though.
As for Nismo, they've stopped production on at least some of the 3rd gen Altima stuff, such as suspension. And one guy actually lost power (dyno proven) with the Nismo catback.

I'm offended of how you used the word "Ricer". That is not what my car is or what Japanese cars are. I have tastefully modded my car and it's not no rice junk car. See "Rice" to me is a car that is all show and no go. Yes, there is domestic "rice" also. The term "rice" to me is horrible mods such as aftermarket altezza or chrome taillights, horrible body kits, big oversized chrome rims, decals and company names on the car for example putting a "NOS" sticker on a car that obviously doesn't have nos, ugly paint jobs, bondo everywhere. Now the word "Ricers" to me are people that race in traffic, people that rev at every light, people that have an automatic car that shift to neutral to simulate a manual transmission car and take off and immature drivers. Sorry for my rant just wanted to clear things up a bit
Your car is nice and clean and I really like the color. But I will say that one thing I think is rice is 30,000k HIDs. Actually, I think that any HID in a non-HID housing is rice but especially the blue colors. There are good reasons why that is illegal everywhere in Europe and North America. Other than that, nice ride.

Shoot, I don't have a problem with Japan cars, except they are a bit small for me. I'm a big guy, I need a big car.
Same here. That's why I have an Altima.
