After more than a 6 hour battle with my old y-pipe I finally was able to get my new Budget Y in place. I hoped in the car after an oil change and went for a quick ride. I reset the ECU (moved the screw from left to right twice) and I'm not really feeling all the NEW power. Where should I be feeling the new horses and how long does the ECU take to recognize and work with the new Y? Sorry if this has already been asked...I admit it, I'm a NEWB.

 

Don't worry. Its been mentioned that it will take a few days for the ECU to adjust itself to the change. I felt mine almost immediately based on the butt-ometer.

 

I felt a substantial amount of power when i installed it, but its seemed to fizzle out, maybe im just used to it, but as you can see, my 1/4 times absolutely suck!!

Maybe with my custom B-pipe and new rear exhuast going on later this summer as well as these sticky as hell Yoko AVS ES100 tires, i can knock it down a few tenths..

From what Ive heard here, autos get less of a "butt-dyno" feel than a 5-speed.
Are you auto?
Or, have you taken it to redline, cuz I think its somewhere up there, but im not sure.

 

I'm a 1996 SE 5 Speed. I have a Stillen Cone Intake and the Budget Y. I dont know where i should be feeling the power - and apparently i lost my Butt Dyno - any suggestions on what that is or where i can find one...

 

i disagree with that
i'd think it would be much easier to notice on an auto, because there is less driver influence. like i can shift hard and soft making it FEEL faster or slower...etc.
auto...you just floor it and know what it feels like...and it will feel different when you stick a performance mod on it.

as for the ypipe, i didn't feel gains immeidiately, and i didn't feel much at anytime actually. i went to the track before/after the ypipe, and i ran 0.2 seconds better, however i was launching much better this time, which is supposed to account for 0.2 seconds. and my trap speeds didn't increase

 

hit the highway and you will notice a big dierance

 

Look here and compare the two curves. One is pre-Budget-Y the other is post-Budget-Y. You see the hp gain isn't really prominent until 4500+ rpm.



Dyno plots are for '95 SE M/T.

 

I didnt really notice a big gain at first,but give it a couple of days. You will definatly feel it. It will start picking up right around 4k and keep going like StygianMax stated.

 

That means it would be stupid to get a y-pipe for those with auto trans, right?

 

wtf? It adds FWHP after 4500rpm, if you go WOT the car will shift at 6700rpm (or something close to that, I forget exactly)... It definatly wouldn't be stupid

 

I think you would still see the gains since M/T and A/T both have identically designed oem y-pipes (Cali spec might be the exception) with the restrictive pre-cats. I don't know for sure whether the difference would be the same or not. I'm just guessing here, but I can't think of a reason why the gains won't be similar to an M/T. Maybe someone with an A/T with dyno curves can comment with real data.

 

I disagree a 4th gen automatic maxima with a shift kit "supposedly" shifts faster then a 5-speed

 

So i should be feeling the power MORE after 4500 RPM and it takes a little while to break in - everybody says it takes a few DAYS but does anyone have any idea how many MILES before I feel it? Thanks

 

on the auto you will notice huge torque steer at 4k rpms. the first time i drove mine the wheel nearly yanked out of my hands.

i agree with the statement about the 5spd and auto, in the auto you just go wot and manually shift, so your shifts are virtually the same every time, there is no letting out the clutch softly or dropping it like in the 5spd where you can control your shifts.

 

How can you push the rpm to 4k on DRIVE gear with an auto trans?

 

I feel the difference at aroun 3000 or 3500 rpm. Thing is I barely ever go past 2500 rpm it's kinda useless, until those pesky ricers rev at me at the lights. Then it really comes in handy. After about 4500 rpm, when the intake and y pipe seem to be the loudest, people just back off immediately...

 

I have mine since a month and half and i can say that you will feel the full power of the y pipe like 5 days after installing it. You will feel it!
