1. Intake 5-7hp
2. Y pipe from warpspeed 10-20hp
3. Apexi WS catback 8-12hp
4. UND pulley from Nick 6-8hp
29-47hp
Stock Maxima @ crank 190hp you do the math.
Does that sound about right? That's off the top of my head, so give or take a few, since every car is different.

I've seen y pipe and popcharger make 170hp at the wheels. So add a couple for what you have done.

In my opinion:
1. Intake: 3-4HP
2. Y pipe: 12-18HP
3. Apexi WS catback: 4-6HP
4. UND pulley: 5-7HP
5. Tranny cooler(i know this not help hp)
Total gain at the wheels 24-35HP. A stock 5-spd is about 165HP at the wheels. SO you shouldbe dynoing about 189HP at the wheels. I think my lower range estimate is more accurate to what you'll get since the compounding effect of the mods are not as effective as single mods sometimes.
Check the dyno forums and you should be able to find exact numbers. Remember that each car is different and responds to mods differently.

4-6 hp sounds much better for the catback

3-5 for the B pipe from smoother bends and 1-2 from the muffler for a better design... not 8-12hp

B pipe is 8 hp http://www.motorvate.ca/mvp.php/522 now add a muffler, what do you get? 8-12 hp.

on the page you just posted "As you can see PEEK numbers don't always tell the complete story. If you have a broad torque curve like the VQ30DE, then peek numbers may not matter. It is MUCH better to have this type of increase over a wide RPM band." he got 8 peak, essentially 2-3 across the whole band...look at the ENTIRE dyno. what if you lose power across the band and get 20hp at redline (mevi for example) was it a gain or a loss? anyway, back to B pipes http://forums.maxima.org/showthread.php?t=236185

As tested on the dyno with my 5 speed:
HKS intake, Y-pipe, muffler = 175fwhp/192fwtq
STOCK intake, K&N panel filter, no intake resonators, y-pipe, muffler = 174fwhp/192fwtq
As you can see, intakes do VERY little for these cars. It's mostly a noise mod.
An automatic 4th gen with just a y-pipe alone will make around 165fwhp. The same Maxima made 154fwhp bonestock. I've seen it with my own eyes. Y-pipes do not gain 20hp. Try about 10-12fwhp. A b-pipe is good for maybe 2-3hp. I'm no slower at the track with my OEM b-pipe vs the two aftermarket b-pipes I've used. Muffler wise, maybe 1-2 hp. Catback as a whole, maybe 3hp. As for the UDP, I gained ~4fwhp/fwtq and drop ~.1 in the 1/4 mile.
An automatic with an intake (any style), y-pipe, catback, and UDP should make around 170fwhp with ~15.2-15.4s@90-91mph assuming a 2.3 60'.

UDP not only gives some power, but helps spool faster, so can give more results than just a B pipe or other small mod... i like Daves advice as a whole, and the numbers are very sound
*edit* hes right about the correction factor too, i thought it was high, but didnt know what normal was supposed to be

Way to knock a dose of reality into this thread. Thanks Dave.
I too have similar dynos to prove the same.

His baseline dyno was actually pretty low. Something was 'not right' with his car. By the time he got a y-pipe, a few other things must have been fixed because his y-pipe gains are quite phenominal... definetly way above average and one of a kind. As I said earlier, every car responds differently to mods. As Dave said, 10-12hp is about right for a y-pipe (at the wheels).
B-pipe is far from 8hp... and a muffler is almost as negligible as an intake which Dave pointed out). We're talking 1-3hp give or take which is nothing on a 170 - 190hp car.

speedemn :
the tranny cooler will help for long life for all tranny parts, as you know the high temp will kill it, so the best way to take care is making the temp goes low, the radiator is not enough for the tranny to keep good temp, so you can add a 404 tranny cooler for pepgirls $59 and your tranny will working fine and low temp on 1/4 miles, racing, etc.
DAVE: i hope i would get that times....with intake and y pipe i pulled 15.99, so i really hope to get low times.

i think you should just dyno. since everyone has own opinions or results from there experience. I have all same setup, just UDP not instaleld yet, and i can fell the power gain. (no cat), for some reason though at high rmp's my car redlines quiker. not sure what mod would do that?
im gunna go to get my whip dyno'ed some time next week hopefully.

how the hell did you do 15.9 at the track? my best time was 17.2 with this setup....greddy catback, budget y-pipe, and cai. took out my subs, spare tire, and was riding on 18s. does that sound wrong to you guys or about right? oh and my car is automatic.
