exhaust hp gains
The computer will do nothing, if you are tlaking about the sotck ECu. YOu could get an upgraded ECU that raises the rev limiter, but this will cost you about 4600, and most people find it to not be that helpful unless you're boosted (N02, Turbo, SuperCharger)
The Exhaust is about this:
Intake - +5hp, +5tq
Y-Pipe - +12hp, +12tq
Cat - +0-1hp, +2tq
Exhaust - +1-3hp, +7tq
Now If you are boosted, it's more like this:
Y-Pipe - +15hp, +20tq
Cat - +4hp, +4tq
Exhaust - +5hp, +19tq
All 3 together w/boost (Because they compliment each other) - +30hp
Of course, all of these are from my personal experiences. Results may vary.
For the most part, the stock Intake system can be worked on, as well as the Y-pipe. But the Cat-Back in the car is already pretty efficient on a Naturally Aspirated (non-boosted) Maxima, and the gains for a Cat-Back are minimal.
Oh, and the search function works wonders.

because I'd like to see you put a new ypipe on a turbo maxima.. kinda like honda owners listing headers and a turbo..

But there's some debate about that.

Actually, from what I hear, the best all around intake out there is the FrankenCar Hybrid.

I've seen a few dynos where y pipe alone gave 16hp and 20tq. VeeTec's dyno for instance. I dont think thats the norm. With just intake and Y pipe I was up 20hp and 25tq from stock, so these estimates are good, plus or minus a few hp.
In the 1/4? Probably good for .3-.5 seconds and 3-4mph.
