so i'm thinking about getting a Warpspeed y pipe for my 2001 SE... is it worth it or not? i've heard from a few people that it is worth it but i wanna know what i'm looking for in a performance gain... thanks

 

It's definitely worth it. You'll gain about 10-15hp.

 

headers ftw if they are legal where you live. Y pipe is next best if you cant get headers

 

^ Y pipe is better than headers for 5th gen...headers are better for 5.5 gen

 

oh yeah? never heard that before... whats wrong with headers for 5g? I dont understand how just a ypipe could be better vs. headers

 

Weird

 

What?

Longer runners on headers make more power than just a Y on stock short manifolds. And equal length downpipe means you get sick sound...especially with a cat-back.

On a 5th gen, the Y replaces the precats so thats where you see *most* of the gains, so if you don't wanna install headers then you wont be missing that much.

 

not true, a y pipe on 00-01 will give more power than a y pipe on an 02-03 cause the y on the 00-01 removes the precats and doesnt on the 02-03. headers make more power than both.

 

yea i guess i worded that wrong...meant y pipe would provide better gains on a 5th gen than it would on a 5.5 gen

 

ok thanks everyone for all the info... i think im gonna be getting the y pipe this weekend and ill let everyone know how it goes when its installed

 

hey guys i have a question.... i have a 2001 nissan maxima and i think both of my pre cats are bad, im not 100% sure its them but it smells of rotten eggs bad and i took it to autozome and the guy said it was the bank 2 cat or somthing of that sort.... im new to maximas so i dont know much but would the Y-pipe replace the cats??? i live in ky so i dont have to worry about emissions and all that. also will i get a CEL and what all will i need. im trying to research things but i keep getting stuff for the 3.5 motor maximas. also where is a good cheap y-pipe for the 01 3.0 maxima... thanks guys

 

Get a Warpspeed y-pipe. With that y-pipe the pre cats are removed so you get nice gains and won't have to worry about pre cats ever again. You won't get a CEL either.

 

im gonna be honest here... i have a cattman y-pipe on my 00 and I really dont notice that much of a gain. I mean when i first put it on, I got nice sound and a better pull but Ive noticed that the ECU/other sensors fixes itself over time and "dumbs" everything back down to factory specs..ie: adjusts fuel and air etc.

Ive driven my friends 00 i30 (stock) and I personally think it drives better than my car. Maybe its the fact that I do have 150k and he has about 80k on the odo. I dunno, someone tell me something I dont know...

 

I will be removing my Front OEM Fed Spec Manifold, CustomMaxima Y-pipe and test pipe from my 2001 soon. Anyone want to make me a reasonable offer? I also might let my OEM CA spec. manifold go (removed with 20K on them). If serious, PM me.

 

Were you not happy with your Y pipe either?

 

Anybody else feel the same way as he does? Im thinkin bout getting a y pipe for my 96

 

Wrong forum, but yes I would get one. Makes a huge difference. It was one of the best mods that I have done.

 

The Y-pipe is a significant improvement, but I now have Cattman headers Y-pipe, and high flow Cat. I no longer need the CustomMaxima.com Y-pipe and front Fed. Exhaust Manifold and OEM Cat. I am also considering keeping the CustomMaxima.com test pipe. Both the Y-pipe and test pipe are hard to find.

I am told that the reason the ricey sound is the test pipe. I now want to get the maximum out of my Maxima at this point.

 

The ECU doesn't make any adjustments at WOT, which is where the gains of a Y-pipe (or any mods for that matter) are found.

Maybe your variable intake is broken? Or just a tune-up is needed.

 

yup check the vi

 

fed spec 00 has precats...y-pipe gets rid of them

cali spec 00, all 01-03 has precats...y-pipe does not get rid of them...you need headers for that

for an 00, the y-pipe is the best single performance upgrade avaliable

 

The 01 CA to Fed mod removes only the front pre-cat and keeps the rear pre-cat which premits the best flow with the addition of the aftermarket y-pipe. It is the best and only configuration without going to headers.

 

this aint no disney ride lol

 

what do you do with the other o2 sensor thats left over? just curious, i may have someone interested in the manifold and ypipe.

 

To avoid "check engine" light, the use of an O2 Sim is required. There is already an extra O2 bung in the y-pipe for the other O2 sensor. If someone is serious about purchasing the y-pipe and manifold, I hope their first purchase offer is a good one, a second bid will not be possible.

 

I've read of a few issues with the Warpspeed on the 5.5. Noisy and banging/clunking to be specific. Anyone with one installed on a 5.5 experience this? From the pics I have seen they do look to be of good quality with a layout that should aid in exhaust flow.

Is this the y-pipe everyone is talking about?

 

On a 5.5 there is no real gains in adding a y-pipe. In order to get gains, headers need to be installed so that the precats are removed..

 

I have a 01 AE and the CustomMaxima.com Y-pipe (e.g. resembles the Stilleny-pipe that is no longer available). Because of budget limiitations at the time and known problems with the front manifold, I chose only to replace the front manifold only with intstallation of the y=pipe. If the rear manifold is replaced, the gains would be more, The installation of headers would release/produce the optimium horsepower.
