I just installed my stillen y pipe today and I just took it out for a spin. I can hear a bit of noise difference ,but the car feels really sluggish off of the line. Will it go away once the ECU balances out some things? The pipe has only been on for a few hours. This happen to anyone else?

 

Inquiring minds want to know !
I'd like to know before I put mine on too....don't want to loose too much low end.

 

Just wondering why people care so much about losing 2 hp beneath 2000 rpms?

 

I don't think that should be happening anyway....someone whip out a dyno graph.

 

You shouldn't be losing any low end. It's definatally YOUR car.

 

I agree.

 

I lost a TON of low end after installing the Stillen Y, Random Tech Cat and Greddy Cat-back (I did them all at once so I am not sure which part did what)...its hard to smoke the tires. The problem with losing low end power, especially if your auto, is that by the time the power comes you've lost. That is the main reason I got the Nitrous...forget about the loss of low end power...its controlling that power at 25mph thats the problem now.

I am debating on buying a CAI instead of my Stillen Pop to bring some low end power back when I run NA.

P.S...I heard people lost low end power from several people...

It's got to be the RT Cat that made you lose low end power. I've got a dyno of a 4th gen that has intake and exhaust, before and after they added a Y-pipe. But we don't have an attach feature anymore so if anyone wants me to email it to them drop me a line.

 

I don't think its exactly that...I am sure the power is there...it just doesn't seem like it is off the line...it seems to take a long time to get to 3500 rpm's...

Here is a quote from Ben's Website:

"Stillen also makes a mandrel-bent intermediate
pipe, which they also call a B-pipe. The B-pipe
takes away the stock resonator (shown in pic).
I have the B-pipe and in fact ran with it for quite
some time, but in conjunction with the Y-pipe and
the Stillen muffler, it was just too loud for every
day driving. The loss of low-end torque was also
too much. So I decided to put the resonator back
on. I'm happy with the way it balances everything
else out. I found out, though, that the muffler for
the 2000 Maxima is a variable backpressure unit,
so I have one on order. I'll be putting the B-pipe
back on and rely on the muffler for backpressure."

I think it's the Cat-back and the Y-Pipe combined...

Well whatever is causing a loss of low end, my personal feeling is it's not the y -pipe. My car pulls harder throughout the powerband. I can gun it from a 5mph roll at 1500rpm in first and immediately roast the tires. It seems like my low end is fine.

 

You have a stick, not auto...stick will pull no matter what...its different...

 

There is an easy fix, just buy a protorque stall convertor. It will give you more launch rpm to negate that "lowend torque loss". http://forums.maxima.org/search.php?...der=descending

 

i don't know...maybe it's my car...but i can't do a burnout wiht my 5sp...simply by WOT at 1500rpm...my power usually doesn't kick in till about 3000...ive done that a bunch...gunning it at 3000 and getting a ton of wheel spin...just my 2 cents...

 

well I drove my car around last night and the loss of low end became less and less apparent. I think it felt sluggish before because it was being broken in. I still feel a little bit of loss, but I also have a CAI sitting in my garage waiting to be installed. I hear that will also give me more low end than my POP chrager. I am very happy with the pipe though, it's a great buy. I've never felt that much power from my max on the highway. It put a big smile on my face.

 

Put the CAI in and you will get that low end back. I have HAI and have that damn pop lag. I am putting in very soon a:

Y-Pipe,

CAI,

2.5" Custom catback exhaust with dual sides


I expect the CAI to balance out the "loss" I may get with the exhaust setup, and hopefully have even more low end pull than I do right now. (stock, and popcharger)

 

I also have that pop lag. The CAI goes in next week so I'll let you know if it balances out at all. I'm thinking that it should make it nice and quick. I'm also wanting to get either the apexi WS or or the Greddy SP catback system. Would I loose any low end with that? I know exhaust gains top end power, but i wasn't sure if I'd lose low end.
