yea...i could sit and read thru the thousands of posts on the warpspeed y-pipe, but its 3 o clock and im feeling lazy...

just got my pipe installed yesterday. shout to maximathug for hookin it up. i feel the gain in horsepower...and my favorite part is my car being able to push my 18's like they were the stock 16's

first question: how long does it normally take to get that god awful smell from the exhaust once the pipe is on??? that isnt permenant i was told, and will stop soon. just wanna find out other peoples experience.

second question: after installing your pipe did your infamous Check Engine Light come on????

third question: in your opinion what is the best cat-back to match up with a y-pipe...when i say best...i say not extremely loud, no rice, and good pick up

fourth question: i've been hearing funny things about how having the wrong exhaust set up can end up giving you less power with the more you had to it. for instance...if you have a y-pipe and headers, but u have a huge exhaust, u will lose some backpressure (or something like that) that will actually make you slower than if you had a smaller cat-back

fifth question: how necessary is it for me to now get a tranny cooler with a y-pipe (auto drive)


btw...i believe the o2 sensors are on correct, and there is no evidence of exhaust leak.

 

Have you pulled codes from the ECU? Possibly the O2 sensor got damaged slightly, or coated with lube from the bolts???
Also, backpressure is always bad for the exhaust. However, if you have too large of a diameter, the exhaust gasses will not flow as effeciently or quickly, and you will lose power.
I'm not sure about the other questions. But, I don't suspect you'll need a tranny cooler with your manual tranny, with just a y-pipe and cat-back. You hear about auto guys with the drop resistor mod., spray or boost, adding the coolers. Anyway, hopefully someone who actually knows for sure will chime in.

 

if my light is still on tommorrow then i am going to check the ecu codes over at autozone...really hope the sensor didnt mess up...how much would a new one cost? do u know off hand roughly the amount?

im not too familiar with the drop resistor mod...can u drop some knowledge on me with that one....do u think i would need the tranny cooler if i got the MEVI ?

 

the smell went away after 1 day... no cel, in my opinion (from hearing) the best sounding catback matched with WSP Y pipe is Apexi WS, and I don't see why you need tranny cooler with Y pipe

 

1. I never got the smell cause I washed and degreased my pipe prior to installation(like warpspeed says to do)

2. I never got a cel, probably cause I was real careful with the o2 sensors when I put it in.

3. Personally I am going with a custom catback with a dynomax muffler, to keep it quiet. it wont sound ricey if you get a resonator!!!!!!

5. this is true, and the biggest I would go is 2.5 inches

6. A tranny cooler on a manual???? Its not nessasary for one, and I dont even see how you could get on to work, there is no pump to move fluid through the cooler, like in an auto

 

Word to what 96maxdaddy said.
1.No smell that I remember.
2.No CEL.
3.Custom catbacks may seem cheaper but are not ultimately and they won't be mandrel. SP2 all the way baby. Do it right the first time.
4. Its all about the exhaust energy. Backpressure doesn't exist in a modern four stroke engine.
5. No, its not possible to have a tranny cooler without doing some custom work.

Front o2 sensors can be found at www.oxygensensors.com. Get the Boosch. Maybe people have had extremely good experiences with Boosch over anything else including me. If I recall they are around $70 shipped. Saving $10 isn't worth it in the long run. Also, why are you replacing $60 worth of plugs when they might not need it? Check the code and work from there. Another example that an OBD-II reader should be the first mod anyone does.

 

sorry bout that one mistake...just edited it...i have an automatic (should have been sleeping instead).

i should have looked at the org more about the pipe, i didnt know i was supposed to wash and degrease it. it smells like eggs.

i most likely will be getting the sp2 after my drop is complete.

damn, i really hope my o2 sensor isnt messed up. $70 could easily go into that sp2 setup. i will be finding out soon what it is.

since having a tranny cooler wont be neccessary would u say it would be a good addition?

 

whoa there chief, now that you tell us your an auto it changes some things about that cooler. First, you car should already have one( a small one). This should be enough for a compleat exhaust and an intake. I would start looking for an aftermarket cooler if you were to do any more than that.

 

I'd say the reason why you are pulling codes is because you didnt hook your 02 sensors on right. It's imperative that they are on right. Check each and every one of them. I'd personally get the SP2 for a wsp y pipe. Im getting that soon.

 

1. One day of driving (60 miles for me)
2. Yes; O2 sensors were dirty
3. I have the GReddy SP2. Once I had an additional resonator added to the b-pipe, it was a perfect mate to the Warpspeed y-pipe.
4. While backpressure is not necessarily good, it is no necessarily bad either. As some others have touched on, you want an efficient flow of exhaust; 2.5" should be the limit unless your putting a lot (way more than NA can give you) of horses down.
5. Not at all.

1. Don't know, got mine installed wednesday and it still smells like rotten eggs

2. Nope, waiting for it though. I'm gonna see about replacing the O2 sensors soon anyways.

3. Find a reputable exhaust shop and have them make you a custom RESONATED 2.5" bpipe and get the Dynomax Super Turbo Muffler #17748. You can get the muff from summit or I think Advance sells them for cheaper. No rice present at all!

4. You actually want it bigger as it goes back. So, stock sizes from ypipe to cat, then max size of 2.5" catback, otherwise the gas velocity will not be great enough to properly allow the gases to escape from the exhaust.

5. I would look into a auxilary tranny cooler regardless. That was one of my first mods. And worth every penny! Just get the B&M cooler instead of the Hayden (which I got ) I will be changing to the B&M soon. The reason is that the B&M has a bypass that allows fluid that does not need to be cooled to recirculate back through the system so that its not 'overcooled'.

Have fun

get a stillen muffler, and either a resonated B-pipe (warpspeed, or like other guys said, get it custom done at a shop)... but go with STILLEN!!!! the best looking, and best sounding muffler for a maxima!

 

True that, after I got my warpspeed I bought a courtesy b pipe, carsound cat, and stillen exhaust (Thanks GlacialBass). I love the low end sound of the combo, great deep sound...but GlacialBass is workin on gettin me a new exhaust because he belives there are some loose welds in it that are giving it some raspyniss in the higher end. Overall I love the combo!!

 

my set up: WS y-pipe, RT cat, OBX cat-back(2-1/4")

my opinions on it: I love it! The OBX paired up with the WS y-pipe gives a nice hollow tone, without sounding ricey. It can appear loud at times, but it's never bothered me that much. The smell form the y-pipe went away after a week or two. The oil/grease that's on it just needs to burn off. I never got a CEL when I put it in. Also, I had my VB mod and tranny cooler done at the same time.

 

Now what is that i hear of gettin a new cat with a y-pipe. Please explain.

 

Some people live in areas where the bolts rust on so badly, it's easier to replace the stock cat when you replace the y-pipe as well. An alternative is to have a muffler shop cut off the bolts holding the y-pipe to the cat.

1. few days...dont worry it will go away

2. no it shouldnt trip any code if it was done properly. if it did maybe the o2 sensors arent in properly. check your ecu it might be something else.

3. apexi ws no rice at all no drone at cruising speeds perfect growl very agressive

4. if you are na you dont want anything over 2.5" in diameter

5. dont know im 5 speed

 

i've got the warpspeed y-pipe, magnaflow cat, and the greddy sp2. but too damn bad i can't give an option on it yet cause GReddy has had a HUGE bad order. i ordered it 2 months ago...still not here. they said that they'll be sending it out on tuesday and i should have it by the 7th. lets just wait and see if that holds true. so i'm just waiting for that to come and then me and a buddy of mine are gonna pop it up on a lift and take care of it all in one clean shot. this wait's killin me tho.

 

Took a few days for me to rid that burnt wd-40 smell. I didn't throw the CEL, and I don't plan on putting a noisy exhaust. I found out yesterday though that 3 of the bolts that hold the cat into the manifold came undone...which solved the noise/ vibration issue I've been having.

 

1. Maybe a week. There is a coating on there that burns for a little while. It will leave eventually.
2. No. CEL didn't come on.
3. I would not replace the stock cat(it does not really add any) or the stock resonator(it does not add anything but a lot of noise to put a straight pipe on for this) or the stock muffler (you might not get another .5-1 hp. I would get a 2.5" piping custom from a muffler shop for about $50 or so. You should be good to go.
4. You can get too big for the exhaust if you are NA, but you should do pretty good at 2.5". I would not go to 3" unless you are turbo/supercharged.
5. I don't think it is necessary at all for you to get a tranny cooler with y-pipe and b-pipe. You should be good to go.
