there was one somewhere on here or youtube with a g35 setup sounded pretty good but this is the sound i was talking about guys...damn thing sounds sick... good job man...

 

hey, im not jacking the thread but i just ordered a warpspeed y pipe. is it really that raspy and ricey. this really worries me as that is what i did not want along with probobly anybody else. should i just buy some random resonator and add that in after the y pipe? ill have a nice muffler but still?

 

umm yes you're jacking the thread. if you weren't you wouldn't say it. ANYWAY...

every exhaust is different. a difference in a Y-pipe may or may not change the sound/tone of the car.

if you want it quiet it's highly recommended that you get a resonator.

 

You will notice little to no change on the exhaust note with a warpspeed y-pipe as long as you have the stock exhaust system behind it..It will change drastically if you add any type of high flow/open type muffler to the car, so if you don't want rice-a-rony, leave the stock muffler on it..

 

i have the WSP ypipe and the stock muffler, however, i deleted the resonator, and it sounds pretty good at idle, but not-so-great when revved in neutral (well, i don't like it anyhow). i'm getting a Q45 muffler and putting a resonator back on, and one of these days (either by way of a GD, or just doing it myself) the ELYP

currently:

 

besides the **** dyno and the tone/sound is there really a gain in power for ELYP?

 

and gas mileage... 505 did you ever get to start metering your MPG with the new pipe on?

 

505max - I understand you modified your original ELYP design to make it closer to true equal length.

Could you post of picture of your new, closer to truly equal version of the Y-pipe?

I spent enough time underneath the car a couple weekends ago to decide for simplicity, I am going to rule out the more complicated idea of having the 180 section oriented horizontally and modifying both pipe, and instead go with your simpler design with the vertical 180 degree bend (although tight), and leave the longer secondary pipe unmodified.

 

You deleted the resonator or I did?

...Just stopping by to bust someones *****. Once you get a more free flowing muffler it will sound very nice.

 

you did

well, it was all that one piece bpipe anyhow, so technically 'you replaced it with some pipe that didn't have a resonator to start with' i guess. but i think i'm gonna have a resonator put back on, and i'm getting a muffler from chris this week that i'm just gonna hold onto and after i get the rest of everything settled out.

 

VG30e has a full WSP exhaust and I dont feel that it gained any power ( lost if anything ) just gained a bunch of droany noise. Do you know a set up that will help. I figure yours sounds better because you have a VG30DE....story of my life...always get the short end of the stick!!!

 

lost power? you probably lost low end torque but gained some up top.

VG30DE?

 

Yeah it's the Japanese version.

 

WTF?

 

We're riding you for referring to the VE30DE as a VG30DE. It's all good.

 

oh yeah....well that too.

 

So no word on whether WSP will manufacture these or not?

Neeeeeeeed moar. aftermarket for our dying gen :P

I was considering getting a y-pipe this summer and hell, if I can get it equal length it seems to be marginal increase of hp / mpg over the unequal

 

I would like to know about this also. My WSP Y-pipe which I got back in 2002 is starting to look a little rusty. It's also possible that the flex section is starting to make some noise. I only recently got the engine mounts fixed, so that flex section probably got a work out for a few years.

My question is can an aluminized steel exhaust pipe be reconditioned by coating it with anything if it doesn't have any leaks (besides the flex section which can be replaced) and the rust is only on the surface? If so, then I may consider keeping this one and modifying it into an equal length Y-pipe. Otherwise I will have to get a new one.

If anyone know the status of a possible ELYP from WSP please let us know. Thanks.

 

I'm in the process of making the tight radius bend for an equal length y-pipe (which will mostly be a copy of 505max's design.)

I would have welded this up, but I ran out of Argon gas in the middle (I'm using TIG welding.)



This started as a mandrel "U" bend with a 3.0" centerline radius. You can see some of that radius to the right. With several sections removed, I am tightening the bend radius up to about a ~1.5" centerline radius. This will help it fit nicely under the car.

 

Lookin' good!

Is your car lowered?

 

505max - thanks!

I am at standard ride height.

 

505max - got any pics of your newest ELYP design (you mentioned you had shortened it since the initial design?)

I finished welding up the tight bend:


It was some good TIG welding practice for me.

 

Thinking about str8 back pipes good or bad idea? and what kinda of magnaflow muffler is that?

 

 

wouldn't a bend that tight hurt the flow a bit?
looks kinda messy for TIG...but still good.

 

if it's surface rust then it can be sand blasted and ceramic coated.

 

i'm 90% confident that WSP won't make it.

 

I'll bet it impedes flow a lot less than the factory equal length Y-pipe. (Have you seen how tight the bend is inside it?)

And thanks for your honesty about my TIG welds.

 

good point...but would a different design be better?

if it's functional then it's good enough for me. beats the bubble gum welding that i've seen others do.

 

Sounds really good

 

what's that got to do with a ypipe? and by pipeS you mean 2 pipes going to the rear of the car? how are you going to run dual o2 sensors? ecu won't run 2. how are you going to fit 2 pipes in the tunel? what size are you going to use? where are you going to mount the 2nd muffler? what were you smoking before you made that post?

 

Im not talking about 2 of anything. Im talking about the elyp isnt it a str8 pipe that connects two into one at the same point? I guess i should have said without a 'Catalytic Converter' but i dont want my car to sound like crap either ive seen it done to a few cars around here and they are dumb loud. I see how u misunderstood it.

 

there's nothing straight about it........ if you want to go catless, that's a 'test pipe', which people do, but the ELYP has to be curved like mad or else it won't be equal length. here is a pic of a stock ypipe vs a wsp (non equal length) ypipe. note how the rear bank pipe is short and just dumps into the collector thingy? well to make it equal length you have to to forward then back again.... hence the bends these guys are fabbing up.

 

Ok I guess I've been looking at this the wrong way because I asked one guy if the ypipe on ebay was one and he said yeah it was i guess it was but just not equal but I do see where its different and yeah I do see the work that has been posted. about how long would/should it take someone to fab it? Im going to a guy that does exhast systems and other stuff for a living but im not sure if he knows about this he told me that it would be about $120 to do it but i dont want a crappy ricer sound if u know what i mean.

 

come to raleigh, go to this shop called RJ's Custom Piping, and let him have at it. he's the one that made aaron92se's custom ypipe for his 3.5 swap (for $300). the man is a magic-worker. he has a mandrel bender IN-HOUSE. that is a VERY big deal. not many independent shop owners are willing to shell out 6 figures for a stinkin' bender. the advantage here is that he can do more smooth bends with less welds and joints than someone could with pre-bend pieces of pipe.

o and if you're wondering "well how familiar is he with imports? he's probably just another muscle car guy".... the dude's daily driver is a RB25DET 240z. yea.

 

The bend is just as tight as mine, but his is better. If the bend increases in radius, you'll lose ground clearance... Of course, any bend hurts flow, but do you think that the oem bend is better?

 

OK... another progress update on my WSP Y-pipe equal length modification project!



I am fully committed to what I call "phase 1" - modifying the rear bank's secondary pipe to make it longer (I already removed from my car, and hacked up the WSP Y-pipe, including amounting flange which is pictured above). This will make the Y-pipe much closer to equal length, but not completely there.

Phase 2 will be modifying the front bank pipe to be shorter, to make it truly equal length. (I determined with a different path, with the pipe cutting closer to the front of the oil pan, it's length could be reduced by up to about 4".) I'm not sure if I'll do both phases at once, or try it out in between... depends, we'll see.)

 

Great news on this also... The shop where im going they have the machine that will bend the pipe ill post pix or some good vid when complete i still dont really know what muff i should get...but thanks for the help man...

 

Nice work!

I guess I should make a new video with the slightly more equal length version...

 

Are you sure that it won't hit the oil pan on your VG? I'm almost positive that your design wouldn't clear the VE's oil pan.

FYI, my design barely touches the oil pan...
