Y-Pipe on - disappointed? Please read!
Hey guys, I recently got my Warpspeed Y-Pipe installed, and I must say, I am very disappointed. I realize that in all the excitement and anticipation of getting it on my car, I may have hyped up my expectations a little, but I don't feel even an ounce of a difference. I examined the Y-Pipe thoroughly before it got put on, and everything looked good. I am pretty sure the install went OK, being that I was watching the whole time. My car has about 140,000 miles, no codes, decently new plugs, air filter, fuel filter, etc. Basically, everything is taken care of, but I saw no difference whatsoever. Has this happened to anyone else?
Sincerely,
Maurice

seeing how your a GLE like myself i would be assuming you are an auto. Well its harder to feel the increase on a auto, from what i read the y-pipe helps flow better at 3,000 RPM +, overall there are gains but i think most people speak of the gains in the higher RPM's a lot more. If you drive the car normally, i dont think you should really notice the gains as much either. It might be maybe only a minor amount of hp at the lower end.
This is what i picked up minus the fact that i don't have a Y-pipe either.

95bluse is right. I said the same thing when I first got my y-pipe. I didn't feel anything. Trust me. You will start to feel the difference soon if you haven't already. If you want quicker results, reset the ecu using the screw method.

Recently, I had my maxima dualed out and discovered the same thing. I have to agree with the previous posts, stating that being an automatic, you will not feel the increase in power unitl you are in the 3000+ RPM range. Hope that helps a little.

intake mod = more low end power (<3000 rpm)
exhaust mod = more high end power (>3000 rpm)
You'll notice an intakes permormance benefits more off the line than at higher speeds (not that it wont gain performance all over the chart, but more so down low). Your y-pipe won't give you a noticable difference from a standstill, but you'll feel it pull more once you get to higher revs (and resulting speeds).
exhaust mod = more high end power (>3000 rpm)

I just installed an HAI and I feel really no performance increase, the sound is nice but little increase. Also intake mods help out more on the top end of the powerband.

You do... it's heavy and has pre-cats...
If the atmospheric conditions and driving style were similar...yes
finally someone that isn't a noob posts.
You will not feel as much of a difference on an auto because your ****ty automatic transmission eats up more power than a 5spd.
also our ECU's dont "learn" so reseting should do absolutely nothing, and for the people that say "it takes some time for your ecu to adjust" you guys are completely wrong!
also intakes have been proven to do absolutely nothing for our cars, the dynos proved that getting rid of your stock resonator actually makes you lose power, and makes your powerband all choppy. No back to back dynos have been done with CAI's to my knowledge, but a short ram or a HAI is not worth it on our cars.
the noise issue i cant really put my input in cuz i kept my stock exhaust, and there was barely any difference, like almost next to none, but on a aftermarket exhaust i have no idea from personal experience.
check for exhaust leaks, get under your car with it running and spray some soapy water around and check for bubbles.

When I read this kind of discussion, I reason:
I have a loaded auto, and it is not a wonderful auto box even by my limited experience, and so I think I'd rather invest the money in audio or suspension or brakes, than buying a Y-pipe and trying to squeeze more power through a fluid flywheel. And it's already quick enough to give most other vehicles cause for concern.

Dualing the exhaust wouldnt really give you any gains, unless it was a "true' dual setup which would be extremly difficult for our cars and it still wouldnt gain too much unless boosted. I dont see how an NA Maxima would be pushing out enough exhaust flow to make use of a "true" dual setp unless extremly modified.

ECU can and do adjust for different circumstances...I guess I should replace "learn" by "adjust".

ur not gonna get a crazy increase in power, but you should have a little and should notice it pretty much right away.
with my 96, the stock ypipe had 2 cats on it. eliminating 2 cats = more flow which = more power.
what did you expect? 100 hp increase?
youll be happy if you go up against a stock 4th gen and start pulling away
i wasnt happy with my ypipe until i installed headers and a cat back
