No way would they put down the same numbers. I finally got to hear a V6 Altima with headers and Greddy cat-back. I must say that it sounds awesome. I was definitely impressed.

y - not that loud. keep the classyness of the car, a littl throatier, but it comes with the territory. as mentioned, on stock exhausts, hardly any noise difference. physically, it only makes straighter pipes, does not remove anything

heads - remove precats....lots of noise....forget lookin like a pimp, you'll be too loud.....and finally....i'd be worried about emissions

but my main reason is noise level.

I would get the headers if the put out significant numbers over the y pipe. Right now I'm not sold on Stillens headers but I haven't ruled them out either. For the time being I went with the Cattman Y pipe (and hopefully soon a TS ECU). I'll reasses my position in a few months when there is more data and hopefully some competition from Hotshot. If it looks good for the headers I'll be selling my Y pipe and switching to headers.

after hearing studman's wav files of his headers, I dont think i'd put them on cause of the noise. they were real, real loud. be nice if they proved to put down some good gains, but dont think I want that loudness. that cattman y-pipe looks great tho! along with a b-pipe, i think that'll hold me over for a while

so how much are people getting with the headers i thought peeps were losing power? i may be wrong

Cdriven

At this point, I'm going to get the cattman y-pipe. And from the looks of the dyno results and Polo's feedback, it makes decent power. Plus, I agree, I don't want all the noise.

But, doesn't the y-pipe for the '02-'03 remove the pre-cats??
Funny thing is I remember reading some threads a few months ago saying that the y-pipe doesn't make power in the '02-'03 Max.

The stock headers can't be that different than aftermarket headers , can they?

I ordered the Y today. Just look at polo's pic of the stock y. That stock y is all twisted up. I feel that the Y will be quieter anyway.

There can be a large difference in loaction and size of collector, primary pipe size and length, materials etc. You made the right choice with the y-pipe IMO

the warpspeed y pipe suxs from what i hear

iTrader: (12)

Thats for sure. I just want to know how the Catman is different ?

Me too..

Thats my $299 question....

so here is the warpspeed pipe:

compared to the cattman pipe:


looks bout the same to me. anyone know what the differences are??

MannyNJ2k2max

iTrader: (3)

dont know the difference but sure dont dyno the same- headers are out of the question 2much$$$$
the y + my budget b should be enough exhaust gains for me- keeps the max sounding aggressive
but not obnoxiously loud-

2k2nyc

Kloogy, was your warspeed y-pipe noisy??

MaximaMan77

I'd say wait till we have more info to go by. Cattman is using a different dyno and the numbers are a little off kilter. No independent dyno's yet.

3 people have the headers installed 2 have dyno'd and Stillen is working with Will & Studman we should have more news soon.

his y pipe was noisy its was loud but dont know y. but all i know is that he didnt like it at all

Now that I look at it the section where the two pipes branch off have
a ****ty looking weld and bend on the warpspeed whereas the Catmann
appears to have a nice finish-looks to be two pipes flush into one-
the distance also from the flex section to the cat is shorter on the warpspeed which could mean that there's less backpressure into the cat
could produce less hp and more sound(loudness) - since the second the gases pass the flex section they blast into the cat -whereas the catmann has more tubing before the cat creates a stream flow into the cat- does this make sense?
the Catmann
undoubtebly has a better design and I bet the finish internally is
of better quality which helps-

Stealin headers
$1100
A B!tch to install (and remove for warranty work)
Provides 0 horsepower gain and you lose 8 lb/ft of torque.

Cattman Y-pipe
$300
Easy to install
Provides 16 horsespower to wheels (??? torque)

I definitely want the Stealin headers.

2 people dyno badly and everyone thinks the headers suck. I can tell you that honestly the THE HEADERS MAKE MUCH MORE POWER THAN A Y-pipe ever will and I proved it on the track. If no one wants to buy them thats fine but its your loss.
