Anyone have any updates on the y pipe and B pipe from either Stillen or Warpspeed at the moment? 30 days? (Last time I spoke to Stillen they said end of June and last time I spoke to Dallas at Warpspeed he said Mid July)

 

Just get aa B pipe custom made... it will be cheaper and better !... Oh, and Youve got mail !

 

WSP is suppose to be comming out with a 2002 Y-pipe any day now. They are currently working on a 2002 maxima. I'm going to call them on Monday and see if there available yet. Keep your fingers crossed!

 

I wont, because Warspeed has promised a lot before Ethan, and what do you own that they made... As far as I know NOTHING ! I hope they prove me wrong !

 

I hope so too I have a good feeling about them making us a Y-pipe very soon.

 

I hope I can get that feeling too. the $$ is here and ready to be given away !

 

I got an email from Dallas yesterday saying they had the test car and were still running tests, however they don't want to dyno the car because it only has 2k miles, and they don't feel it would be an accurate test. I assured him however to try to get this done asap because he will have like 100 orders as soon as it is ready.

 

Please convince me this is true..... I will be a very happy person !

 

I will dyno it as soon as I get it.

 

What about 2001 y-pipe? I'm still waiting for them to build it...

 

Same here....

What is wrong with using 2k federal spec exhaust manifolds and a federal 2k Y-pipe ? In the end you remove the precat and relocate both the o2 sensors. Yes it has been done before and is worth 2-4whp for the manifold conversion.

 

1 HP

 

Waaay too much work for 1 hp, plus money spent on a fed. spec exhaust manifold negate warpspeed price difference

 

There was a guy that tried this on his 2000. It looks as if you'll make some nice gains by moving that monstorous Fed spec manifold, but gains are nill.

 

Desert Pearl tried this on his AE as did I (on both an auto 2K1 Se, and a 5 speed 2K1 GXE). There are really no gains, and maybe even a little bit of a loss in low end torque. The only reason to do this would be to fit a 2K1 Y-pipe on a 2K2. But there is no benefit to doing this on a 2K1 (unless you also do a 2K fed-spec ECU swap - then it might be good for 5 HP or so).

 

Hmm both manifolds can be had for $75-150 shipped? That is the difference between a aluminum and SS y pipe.

 

Here is the dyno http://www.desertpearlmax.homestead..../dyno_269.jpg. It clearly shows an average 3whp gain from 4000-6000rpm, also between 4500-5000rpm there is a 5whp/5wtq gain. I would argue that those are simular/better gains that just adding an aftermarket muffler to a stock maxima. Now Emax has proven that the exhaust manifolds are interchangeable from VQ35 to VQ30. Given there isn't a Y pipe for the VQ35 it would probably only cost about $100-200 tops over a VQ30 Ypipe to do the conversion. I'd figure $325-400 for both manifolds + WSP Ypipe but that's just me . Again what is the problem?

The archiver ownz j00!

 

I just want a SS y-pipe, and warpspeed charges $299 for that. (whenever they'll make'em), Plus 75-100 for the manifold. For that price I can have a Cattman one(and save some $$). I can't use aluminized y's because of the snow.

 

I got both manifolds shipped for $90. I'm going to wait a little bit longer to see if I can get just a 2002 Y-pipe.

 

If you look at what's going on under 3500 rpm, or so, you'll see there's a pretty substantial reduction in torque. I can personally tell you this is a fact. I've tried this mod on both an auto AND a five speed. I hadn't seen this dyno in a while and had discounted this loss initially. If you read further down the threads there's speculation perhaps the dyno operator didn't punch it as early in the rev range as he had with the other two dynos. But I doubt it - there is a noticeable real-world loss of low end. And yes, there is a very slight benefit in the upper rev range - but given that it'll take you longer to get there I would be very willing to bet that 0-60 and quarter mile times would suffer with this mod.

Needless to say I've gone back to using the front pre-cat. For whatever reason, this is a better set-up with Cali-spec cars and Y-pipe.

EMAX - Come to think about it, doing this on a 2K2 may, and very probably will, offset some of the gains of a y-pipe. So I'd just wait for a Y-pipe specific to the 2K2. I can virtually guarantee it's going to need to incorporate the front pre-cat and ideally lose the rear-precat to be most effective.
