anyone planning on getting this? I was told that the whole exhaust system would be $1075(y-pipe,r/t catlatyic conv.,b-pipe,muffler and installation kit). what do you guys think???

 

Not me, but I've heard that the Y-pipe and the catlatyic conv. are useless on 2k2-2k3 Max's. So I would put that money towards the Stillen Headers(about $800).

 

 

why is cattman even going to market this thing after the warpspeed ypipe fiasco. Don't people learn from other's mistakes anymore??

I sincerly doubt that their ypipe, aside from asthetics can be all that different, and i'm sure there will be similar problems.

 

Did you guys ever think that the reason exhaust mods and high flow cats show such minimal gains is because the motor was being bottlenecked right in the center. Im sure once you get the stillen headers the cat and exhaust will show some good gains. Without a larger header the air going through the exhaust isnt flowing at its full potential.

 

CATTMAN makes a y-pipe for 2002-2003's???

 

good question...

 

it is suppose to be out next month but you can never rely on that

 

really??? Is it lisited on the website???

 

no i talked to a guy named brian thru e-mail. here is what he said...Apprently you hear that correctly about the Warpspeed y-pipe. We are in the process of fabricating our new 02-03 maxima/i35 y-pipe right now. I expect it to go on sale in about a month. It is patterned after a prototype that we had dyno tested recently on an 03 automatic, but it was out of town and I do not have the detailed results yet. I do know that it made power everywhere on the rpm band, that it increased peak power 7-8hp at the wheel on a bone stock car (it would be more if the car already had an intake), and that it made more power than that over stock at some off-peak rpms (I don't know the margin of increase and where it occurred in the rpm band). If this engine responds to a y-pipe in the pattern of other VQ V6s, I would guess it made as much as 10-11hp over stock at the wheel somewhere in the 4500-5500 rpm range.

10-11hp, or 2-3 more in a 6-speed may not sound like a lot, but given that Nissan has squeezed about all they can out of this engine, I was pleased to get that much power from a well designed part. As far as competition, I am only aware of the Warpspeed version. I'll just say that the reason we put ours through a more formal testing program than usual was because we were told that the Warpspeed pipe didn't make power -- I don't mean not a lot, I mean none, as in something between -1 and +1 hp. We were first told about this by someone who had let Warpspeed try their prototype y-pipe on his car. He loaned us his stock pipe to pattern from in hopes that we could make one that did perform. Warpspeed then went into production anyway and when people started buying and testing them, many of them reported that it made no power. Nothing unusual about this in the performance industry -- I've heard numerous people admit their parts looked great but didn't make power -- but its not the way we do business and if it hadn't made about 80-90% of the power that it did, I would have canned the project.

So yes, this is a part that's not available yet, but its power is well-demonstrated already. Don't let anyone define what is possible on the basis of what Warpspeed has achieved, our y-pipes consistently outperform theirs.

harmbone2k2,Thanks for the info. I'll be awaiting their arrival. Finally I'll have a CATTMAN y-pipe to compliment their cat-back exhaust that I already have on the car.

 

how is that exhaust anyway?

 

If Brian says it makes power, then it does. I have nearly exclusively Cattman parts on my car.
