Anybody have a pic of what the warpspeed y-pipe is supposed to look like? I bought one off a org member claiming he had on 02' one. So i bought it off him, took all my exhaust apart and everything matches except the rear collector its to long. Not to mention the "claimed" one has 2 oxygen sensor ports and factory has only 1 on there. Anyone?? It almost looks like my old 99' max y-pipe.

 

Did you check the Warpspeed website? I have a Warpspeed ypipe on my 02', it does have two bungs for O2 sensors. There should be a removable plug in one of the bungs.

 

just send it back....ypipes get very little gains on the 3.5 anyhow...hardly worth the trouble of install.

 

How you post pics of the y-pipe you bought as well? That would help too.

It sounds to me like you have a 4th or 5th Gen y-pipe.

For what its worth, here's a pic of my Cattman y-pipe:

 

Joel...check your yahoo email, if you would...

 

sounds like you have a 3.0 y-pipe

 

Got it, thanks. I'll get back to you on it later.

 

It looks like the one in post #4 and i looked at my old 99' factory i had and it is not like that it is like the one above but has a longer rear collector. Side by side the pair looks identical to the ones above. Mine is a cali spec is the one above?

 

Im sure there are some gains out of it, just by looking at it it doesn't look like it flows very well. And intall is easy i will just have to take it to an exhaust place and have it modded. And besides i only paid 100.00 shipped, It was in box never installed, everything included. Well except the bung plug.

All 02-03s are Cali spec.

 

which is why the 3.5 y-pipe gives minimal gains.

 

yeah thats not the one i bought, and if you want to spend 5-600 dollars at least and 8 hours under your car for .15 off your quarter mile thats good for you. If i wanted to spend that kind of money no2 would get you alot farther. For half the install time and you wouldn't have the leaky flange gasket problem alot have either. Why does most people have to be such ****s and negative about everything????? Makes me be proud to be a member.

 

my WS y-pipe has two bungs too. you have to try to push the original exhaust back, have someone help you. and dont listen to the people telling you it gives minimal gains blah blah blah, i did a y-pipe and timing advance and it was good for .4 in the quarter, nothing to complain about

 

please speak english and attempt to make some kind of sense

and a y-pipe on a 3.5 WILL NOT take .15 seconds of your 1/4 mile time.

 

...

 

Refering to the y-pipe has no gains and should go with headers. Yes im aware y-pipe won't add that much horsepower and i no it won't drop .15 off 1/4 < was refering to headers.

 

what do you mean push the exhaust back? The second (rear) collector pipe is to long by like 5 inches. And how did you take .4 off your 1/4 by just this? That is like adding 40 horsepower?

 

Minimal gains eh?? So that means that the stock manifolds are the restriction b/c I keep reading of people gaining like 20HP from headers, and the Y-pipe is supposed to be 13 or something. I've been trying to figure out if the headers are worth the money or to just go with the Y-pipe. Looks like there are too many mixed opinions.

 

Could someone explain a little more details why Y-pipe get very little gains on a 3.5 when it eliminates the 2 pre-cat? How the fact 02-03s are Cali spec affect this? Thanks.

 

. .

 

i cant explain it, but a 14.71 and then a 14.31 is the difference. i dunno.

To the poster above: the y-pipe gives smaller gains because it does not replace the precats like it does in other gens. the precats are the real flow problem and headers remove them

 

I'd disagree here. Desert Pearl's FED to CALI spec conversion (using a FED spec front manifold to remove the front pre-cat) only yielded him about 4 whp over a Stillen y-pipe. Very similar has been seen with the eBay headers, which are essentially stock short tube headers with no pre-cats, unequal length collectors, and an aftermarket type y-pipe. Mr Eous dyno tested the SS Autochrome headers and saw something like 3-4 whp over a y-pipe as well.

Based on that evidence, I'd say that the large gains from Cattman and Hotshot headers are due to the design: the longer tubes and the equal length collectors, and not just due to the elimination of the pre-cat(s).

 

And just to further clarify, for 00-01 CALI spec Maximas, an aftermarket y-pipe only eliminates one of two pre-cats; the rear bank pre-cat that is part of the y-pipe, while the front pre-cat between the front bank header/manifold is still intact. A y-pipe eliminates the one and only pre-cat on a FED spec Maxima.

For 02-03 Maximas, both pre-cats are between the stock headers and the y-pipe, so a y-pipe doesn't replace either of those. You will still see some gains from a y-pipe, but for the money, its not really worth it unless you get a great deal on one. Although, I do agree it is an easy install for ~8 whp gains.

 

errr... Cattman headers cost $800+ and the installation I heard is not easy at all. =( I believe the Stillen headers does not have equal length collectors and is not worth it, correct?

 

They do cost that much but the installation isn't all that bad. With the right tools it can be done in 3-4 hours and I know of people who've done it in even less time.

Stillen headers are not worth it and are the same design as eBay headers with the short manifolds and unequal length collectors. If you want more details, there's link to the thread about em in the Stickies.

 

hotshots are equal length and worth it also and i believe they are slightly cheaper

 

I sent warpspeed pics of the one i have and dallas said that it is for a 2000-2001 cali spec maxima only. So it is for sale!!

 

we never saw pics!! post up some pics to make sure

 

what is for sure? Im sure dallas would know he made it. Are you interested in buying it or are you just playing?

 

well you said its just like the 5.5gen y-pipe above, so lets just see it to make sure. you never know if dallas is on crack for the day or something. why dont you want to post it up here?

 

WOULD SOMEONE PLEASE LOCK-UP THIS THREAD!!!!!!

 

Why don't you just delete the motehrtrucker since you started it
