clipse: good job bro....BUY IT. i'm loving it more and more
Everyone else: i was driving it all ntie tonite and it
1) it sounds REAL nice and it doesn't even sound that loud at all
2) my lower range lag that i had with the injen no longer exists. i pull from low rpm ALL the way through to redline.
i'm loving it....definitely.i still havne' thad a chance to test the speed in my speeding areas, but i will soon. i was stuck in the city all nite in traffic, so i wasn't able to push it, but on a few instances in lower first gear i slammed it and it peeled out through all of first gear. def. caught me by surprise.
tsk tsk guys, just buy it....i'm enjoying it. ypipe + injen + greddy = very nice throaty sound. almost mustang-like.

I know it's not possible to say exactly, but does anyone know what it'll be like with all other exhaust components stock? I got injen because I didn't want loud... i don't want to install this and get loud. Any idea if this'll make a stock exhaust noticibly louder? (sorry if this was answered earlier)

Should I do it ???
Thanks, Anakin Skywalker.

I'm very sorry for the delay, but I wanted to pass along the dyno results I'd committed to provide.
I'd mentioned that it made more power over stock off-peak than at the maximum horsepower, and that's very much the case. Power is gained everywhere -- especially between 4000-5000rpm -- with a peak power increase of 16hp around 4400rpm. Average hp gain between 3800 and 6200rpm is 7.8 hp.
Note that we could have better dyno data in the lower rpm ranges -- No, the y-pipe did not lose power below 3800, they just didn't get the torque convertor locked up till that point. The second dyno, showing the addition of a b-pipe to the y-pipe confirms that the pipe is very strong in the lower end.
Here is the dyno comparing the stock y-pipe with the Cattman y-pipe:
And here is the one showing the Cattman y-pipe (before) with the Cattman B-pipe added (after) [Note that adding the b-pipe would not have "fixed" the low rpm issues of the Cattman y-pipe run -- this run is obviously very solid below 3800rpm.]:
It looks like slim margin, but there's actually a spot where the B-pipe gains 8hp -- that's unusual -- but there are a lot of 4-5hp readings, which isn't bad at all for a b-pipe that leads into a stock muffler.
With the y-pipe and b-pipe together, there are solid 19hp gains over stock in the 4300-4400 rpm notch, and an average power gain of 11.2hp from 3800-6200 rpm. Remember, this was with the stock intake. I do wish we'd had the Cattman muffler tested...
I have copies of the raw Dynapak data, and also a spreadsheet that effectively compares the before and after horsepower data, which I'll be glad to send on request (send me an email). Hope this information is useful.
And, remember, these and all the other Cattman stainless Y-pipes are available for $299 in commemoration of our 5th year anniversary -- sale ends officially Friday, 24 October (but by special request we're going to take stragglers orders Monday).

Wouldn't be much different at all if you're talking about a full stock exhaust system. The y-pipe doesn't replace the precats, the stock system is very "muffling", and not only would it not be loud, it wouldn't be that noticeable a difference.

I was referring to the sound ("it wouldnt be that noticeable a difference"), not the power. The additional power should be quite noticeable.

I don't know what sort of muffler you have one, but if a stock or Cattman Performance B-pipe is in place (both have substantial resonators) you should notice little difference in volume, and a slight deepening in the tone.

It seems to me like the stock pipe is a pretty stupid design. Why in the world would Nissan spend millions of dollars designing and manufacturing a pipe with that big u-turn bend in it? Is there an engineering reason for the stock design?
I like the cattman and I may order but my wife would skin me if I did it now. I just bought the car and I ordered a motorola car kit for my cell phone. Mods will be tough to justify. She thinks the car is fast enough as it is.
So did you guys already have a muffler upgrade when you installed the y-pipe. Sounds like a stupid question but I want to make sure. Are there any pics of the underside of the car? maybe we can see what the pipe looks like installed.
Great write up, btw.

Hey Man, tell your wife that you ARE getting the Y pipe and that is that. You are the king of the castle, You make the rules.
Take it from me, I always do what I want, I earned my money and I'll spend it however the hell I want to.
Do you think that has anything to do with me being divorced twice

I agree it's not the best design, but it's ten times better than the OEM Y-pipe design on my old 3rd Gen VE. On the VE, the rear bank collector flows in opposition to the flow from the front bank.... very inefficient. At least the stock Y-pipe on the 2k2/3 flows in the same direction.

I'm newly married and I don't want to be cut off yet. 
Ahhh, the things I do for love.
But really. There are several things that I want to do the max.
New tint.
Anniversary Edition door sills.
Wood trim
Chrome rings for gauges
Install the motorola v60 car kit.
Eclipse Sun Shade
Pre-luber
And I still have to make payments. I would hate for the credit union to take my fun away.

another question i haven't seen... I plan to buy the gasket kit they offer but is there anything else needed?
Does the o2 sensor screw in? Does it need any "lock nut" stuff?
Or do I just need the 3 gaskets and the new pipe??
thanks,

contains all of my videos, in a step by step (intake, then intake exhaust, and now intake exhaust ypipe so you'll see how it sounded with the greddy and how the ypipe made it different.
3 gaskets and new pipe. o2 screws in.

Alright guys, just ordered mine. The gaskets are now $15 for some reason and my shipping to AL was $25. She said they may have one left for me, but if not they'll be getting more on Monday or Tuesday.

ok, i was finally able to upload some more videos. i need a better DV camera. this is just my mavica which has a 15 second quick video clip setting. not much i can do, but hey, it's the best i can do for you guys.
due to my server having a limit, i'd like it if you could do a save as, and then watch it. last thing i need is 10000 people streaming it...thanks
Crusing from 1st-3rd gear, shifting at 3k rpm
Wide Open Throttle from standing outside
Wide Open Throttle from inside car - missed 3rd gear, smacked redline..DOH!!!!
yes, i had my strobes on...i was bored...
let me know if this helps anyone....as you can see, it really isn't that loud at all....and again, that is with an injen and a greddy, so dont' hink that just the ypipe suddenly created ALL that noise. it's a combination of all that. and standing in front of the car, most of the noise you hear is the injen, with the greddy taking over from the back.
