i think that the y pipe has been talked up a bit much here. dont trash me with flames. i got it expecting a radical difference but other than the sound and the engine revs a little faster i am kinda dissappointed with the noticable pulling gains, what was i to expect realistically? i am still yet to go to the track and see differneces on paper. maybe my hopes were just a little high or maybe i am starting to realize that i just spent a few hundred dollars that was for tuition.


do you think when i take it to the track i should see differences on my times? any predicitions. intake, y pipe, STS, hi flow cat. best run without y pipe was a 9.8

 

What was your 1/4 ??

 

was 9.8 without y pipe.

 

I havent done this mod yet but I plan on it pretty soon...from what I've heard, its one of the best mods for a maxima, hands down

what type intake you have ??

 

Well the 9.8 is not a very good 1/8 time, so you will improve on that I'm sure just by your experience and skill increase that is sure to happen when you get to the track more. If you doubt the power of the y-pipe take a look at VeeTec's post about his before and after dynos... 16 whp and 12 wtq. That's huge for a single exhaust mod on an N/A car. HUGE.

Also take a look at my sig... 14.87 stock and 14.46 with it, backed up by a number of 14.50s and 14.51s... Look at my trap speed. 4 mph increase. I don't think you understand how huge a gain this is, so let me say it again. It's HUGE. .4 seconds in the 1/4 mile is like 5 car lenghts...

 

Alot of times it may not be until you actually see it that you realize how much it changed.

I was also kinda dissapointed with my WSP mandrel bent Y. I think mods get hyped up to much. Maybe it makes you faster but I don't feel a whole lot.

 

did u put your exhaust on at the same time, i heard that with a catback you loose a little bit more low end and gain more on the high end but from VeeTec's dyno he had gains all over!

 

what 1/8 mile should i be shooting for?

 

go to a 1/4 track

i think you said vtec

 

I felt the same way right after I installed my y-pipe. However, I think the reason it didnt really feel faster was because the ECU wasnt used to it yet. Now that the ECU is used to my y-pipe, the gain is really noticable.

I didn't feel a huge difference when I installed my Y pipe. I did feel a difference from stock when I used it in combo with a CAI. The system seemed to breath better especially at high RPMs. Yes you do lose on the low end, but overall I think there is a good gain. In my opinion 8-10 HP (what I would expect from a Y pipe - others claim more) is difficult to really feel. 15-20 is easier to feel and that's what I think the combo of CAI and Y pipe gives (supposedly) ... well I can feel a difference now.

 

You don't really feel a 'huge' difference with the Y... but you do notice the loss when you remove it.

There hasn't been any mod that I could really feel a big difference except one... the S/C... but you pay enough for it.

 

A good 1/8th with the Y-pipe would be in the 9.4 range (~14.6-14.7). .4 seconds doesn't sound like much, but still seems to take forever to chisel away at every .1.

The Y-pipe isn't a night and day differene. Most of the addition power I noticed was from 3rd gear on. My 4th gear is FAR stronger than it orginally was. I noticed NO loss in low rpm power. When you're talking about a mod that gives you 8-9fwhp and 10fwtq on a 3000lb car, you can only expect so much. It is the best NA out there. Nothing offers the same bang for the buck. I wouldn't expect to see a gain of 4mph in the 1/4 mile with a Y-pipe. 2mph would be more realistic. Nealoc's 4 mph gain was probably related to better conditions, better driving, and the y-pipe. A 4mph gain would be like adding 30fwhp in a Maxima. I don't see that happening with the Y-pipe.

makes me less dissapointed when you point out the gains arent as noticable as the loss w/o would be.

 

I HEARD THAT Y-PIPES MESS UP AUTO'S HOW TRUE IS THAT?

 

you guys got to remember regular maintenance.. you can't take the full use of your mods if your car is not tuned up regularly..

if you have sh!tty plugs, clogged FF and bad air filter.. you won't feel any differnce.. because the car is not breathing..

Cashj2002 - thats bullsh!t

 

Thats what I was told that Y-pipes aren't good for auto's

 

here is a little quote for you:

"believe half of what you see and none of what you hear"

 

what does NA(n/a) car mean? Not Applicable?? That doesnt make much sense. Non Auto? Im stumped.

"That's huge for a single exhaust mod on an N/A car. HUGE. "


"It is the best NA out there"

Ive seen it all over the board...

Dont listen to some of these people that dont know nothing tell you a Ypipe is bad for an auto thats just such BS, a Ypipe will help the gases exit your vehicle much faster and smoother vice a stock YPipe which is restricts airflow exiting your engine now hows that suppose to harm the car? a Ypipe will be the one mod that if your picky and your car is tuned you should notice an increase in power, now do notice that a Ypipe by itself wont do much good if you dont have an intake and the catback exhuast. Not to post against you but I noticed the little bit of power right away I took that car on the highway and tested it out. I have a poor mans KN intake YPipe and Greddy catback exhaust.

 

cause thats what you have that i dont have. how do i know that my car is tuned correctly also?
