I was looking forward to getting my Budget Y-pipe, B-pipe and HF Cat installed all week and when it finally happened last night, I have to say I was a little dissapointed on first impression. I'm not sure if my expectations were too high but I have to say I can barely feel it on the good ol' buttdyno.

A few things to point out, I had to bring it to a exhaust shop due to my bolts being grossly seized(stock exhaust went through 7 Canadian winters). They mentionned the O2 sensors and maybe having to replace one or 2 if they got stripped during removal(rust was rampant on the pipe), but turns out they all came out nicely. I also had a new muffler installed...an OEM .

Could some of the O2 sensors still have gotten damaged, and if so is it possible to tell without pulling codes? (haven't had the chance yet and CEL always on from Speed sensor) Is my OEM replacement muffler choking my exhaust? Only other mod is intake.

Sorry for all the questions but I was really hoping for a much better result. Thanks.

 

Y-pipe is snake oil.

No actual gains.

 

riiiight...

 

Kehops, what part of Canada are you from? How much did Budget charge for the pipe? I am thinking of taking a trip to their shop soon but I hear they boosted their prices?

 

Paid 650 for Y-B pipe and HF Cat. Shipped with tax. They have 15% rebate when you buy the package, even cheaper if you pick up. Check out their site for pipe prices:

Umm you cant really feel it much, but the power is there, I suggest you check out the Group Deal forum and buy a Place Racing CAI, i have a budget Y-pipe, and i can feel the 2 together alot.

+Place racing CAI sounds beastly.

 

I already have JWT intake. That's why I'm surprised I'm not feeling the gains.

 

You can't really 'feel' the gains that much but what you should notice is that above 3700RPM's your car doesn't fall flat on its face anymore, it should still pull decently. You won't feel it much on your butt dyno because it doesn't increase low end. Heck, i don't know how anybody feels a 'big gain' on their butt dyno. I felt a gain for sure in the upper RPM range.

LEMAR

 

From what I've been told, the ypipe is the best bang for the buck, I was expecting more bang.

 

Hmmm, I wasnt aware budget changed their site. Thanks.

 

You should let the ECU get familiar with your new toy and post back in a week. You should feel a better.

 

I agree the thing I noticed with the 5 speed is I don't have to downshift to 4 to pass on the highway. It lets my VQ Breathe

 

Anyone else of this opinion?

 

You should have done before/after TRUE dyno pulls. Relying on your a.ss is a fallacy.

 

Not worth it for a Ypipe. If I was installing SC on the other hand...

 

I've heard that too, ecu needs to "learn'" the new freer flowing Y-pipe. Then again, I won't know for sure, I don't have one

 

Thanks for their site info!!!!
I've been wanting to get a B pipe from them but had trouble finding their site.

 

i felt mine when it kicked into 2nd gear...but i prolly was my head

 

Once I get past 3500 Rpm I can feel a nice increase in power. It kinda pulls my head back a bit until the car shifts.

 

Of course your butt will feel the difference with an SC!
It felt good with the Y-pipe and now it feels even better with the B-pipe added on!

 

I don't think you undertood what I meant. He said I should of dynoed before and after ypipe. I said it wasn't worth it, but if I was installing an SC, I would consider it. That's all.

 

So you felt the gains immediately? Any truth to the ECU needing time to adjust according to new airflow?

 

i actually felt my car was slower after the ypipe, straight racing pipe install. it wasnt until i reset my ecu 2 weeks later because of the CEL and let my car run out front for 20 minutes after resetting that i felt a massive boost in the pickup of my ride and i mean huge diffrence i love the way the max responds now cant wait till i get my licence back so i can drive legally... but fyi the y pipe and strait pipe teamed up with my LOUD and Mean sounding frankencar intake is a deadly combo the car is fast now

 

I'll reset my ECU tonight, maybe that'll help some.

 

before i got my y and b pipe installed the max would just fall flat on its face past 4k. Now it really cooks at 3.5k+ this also might be due to my KS being blow and lacking in the low end.

 

What does the ECU control or monitor in the exhaust? Nothing but O2 sweeps. MAYBE the ecu would take a little while getting used to the extra air INTO the engine since it monitors air flow through the MAS, but through the exhaust, hell no.

 

Yea I heard the butt dyno is best

 

You kiddin me? If this thing adds close to 20hp as advertised and dyno tested, then I should definitely feel something, everyone else did. Anyways, thanks for your input.

 

I felt mine alot just now. It felt very cold, possibly due to weather conditions. I can go check it after I drive if you want me too.

 

^^^^^ a.ss

 

The same amount (mass) of air that comes in through your intake leaves through your exhaust. There is actually more mass coming out because fuel has been added.

Sounds like someone needs a primer on feedback control systems.

When the engine is running in closed loop mode, your front O2 sensors monitor the oxygen content in your exhaust. If too much O2 is monitored (lean), the ecu compensates by increasing injector pulse width to add more fuel. Conversely if a rich condition is monitored, injector pulse width is decreased. This moment to moment deviation from the ecu's pre-programmed fuel map is known as short term fuel trim.
The ecu "learning" affair is known as long term fuel trim. After a predetermined length of time if the ecu is always having to deliver atleast a certain amount more(or less) fuel than what the pre-programmed maps call for, this value becomes the long term fuel trim.

All this only applies to closed loop operation. When you are WOT, or accelerating or decelelerating appreciably the ecu switches back to open loop in order to maintain stabilized combustion.
The whole point of all of this is to reduce emissions and improve fuel economy, not to give you a bigger kick in the "butt dyno".

 

then try it...prove it to yourself

its mental

 

I felt them instantly... The throttle responce was better in my opinion.. It really kicks after 3K

 

you should feel it during second gear

 

you definatly notice it from the 100-140MPH range. It no longer takes 6 years to get there.

 

first of all people that say y pipes dont do anything can watch my track vid's. 2nd, before y pipe i was running 16.0-16.2 after y pipe im runnin 15.6-15.7 all day long. For me i couldnt really feel the differnce til after 200 or so miles thats how far it is to get to the track for me so when i got there i was amazed how much harder it pulled in 2nd...though maybe because it was the same y pipe runnin 13's on neal's car .

 

do it up

 

I felt mine right out of the box. It was so smooth and shiny too. Yes it gives more power

 

That's what I meant. but was at work an in a hurry. Basically, if the exhaust is less restrictive (the Y-pipe portion anyway), then you'd obviously be sucking in more air, which needs more fuel = more performance.

 

I felt immediate gains, most of it in the mid and top end.

I didn't reset the ECU. The first 200 miles after the install were strictly open highway runs. The pull is there.
