hehehe
worse....
Look at these figures:
[Stock]
260ps = 256.44hp
[w/ exhause]
282.4ps = 278.53
can't find torque conversion info, but I don't think these numbers are right. But it does result in a gain of about 22hp at the fly wheel.

something seems wierd with that dyno.

remember that there are different types of dynos. i dont know much about it but i know they measure in different ways. in other words this may not be S.A.E. hp... may be some differnt scale... anyone know mroe about dynos?

One other thing, all aftermarket y-pipes will eliminate the precats, not just the amuse, that is the only way to gain substanial power.....

I assume this was done in japan, which means at or above sea level, so if they didnt correct it, it would be lower, not higher. as for different types. it would never be off by that much. the conversion was given. 255hp or so, thats a loss of 32hp, well under 15%, something no one has reproduced so far on the Z.

For one thing, I believe that in Japan don't use Cats, because dont have a law to control Emission(thats what I heard) maybe thats why the Stock HP is higher than us, and thats way the Y pipe of the Amuse System began in the end of the headers(you can see the angle in the Y pipe, that angle do not exist in the Stock Y pipe) In others words if you see the Z rigth under you can see that you have:
Header, Connector, Cats in line, Connector, stock Y pipe and connector.
In my opinion I don't know if that Y pipe is for the States
Maybe I all wrong, I dont know!

tcl please remeber that epa stuff is still state to state
in Indiana we have nothing, no visiual. no checkup, no emissions test,, notta
and in japan thier emissions are more stringent than they are here even in the states that do test. so how do they get away w/ no cats etc? 1. higher octane gasoline over there they get 105 and such.. which is another reason for the higher hp on a high compression NA motor 2. futher refinement of thier products for thier domestic product they tune thier stuff differently over there
so this may just be the case with the Z we'll have to wait and zee

But yes in Japan and Europe the gas is 100+.
We need someone that represents Amuse, to ask a few Questions!

1) The System Eliminates all cats?(with the Y pipe)
2) Where to put the Cats sensors?
For now this are my Questions
Any one else?

nevermind...answered my own question. The muffer setup gives an increase in 11 HP, and then the y pipe ads another 10 hp. I suspect that the y-pipe will do less than that as a stand alone item. Its only worth os to buy the whole system. Woooo hooo, 311 HP at the flywheel.
add CAI 8p= 320hp (flywheel)
then, assuming that this system was run without retuning the ECU, I will say that an ECU tune will take us to 330-340hp at the flywheel. Sweet!
Add underdrive pulley, headers and a port and polish, were looking at potentially 350hp at the flywheel. Am I being optimistic....hope not, cuz those numbers are AWESOME!
Youre gonna eat **** M3!

um i'd say a bit on the optimistic side.
or at least for the gains from intake and exhuast and a chip
the gains from tthe pulley headers and port and polish however maybe more accurate. i've never had a larger displacement motor though so i guess im not sure what type of gains we can expect.
