Amuse Exhausts - New Nismo Versions

Amuse just released their Extra STTI and RS-Silent STTI models for the Nismo 370z dual system. These will bolt up directly with the Nismo dual outlet midpipe.

There are 2 tip designs to choose from as you'll see from the pictures. The "Extra" picture is an example of a single wall tip, while the "RS-Silent" picture is an example of the new dual wall tip. The tips are also 5mm larger than the previous models (120mm)

Another option that Amuse has always offered is a choice of tip burn styles. See the picture below for the different versions.
A Tail = Just the edge burned
B Tail = The full tip burned
C Tail = No burn; just the polished ti tip (not shown in the picture)

Check them out:

Will it fit on a regular 370z?

no, regular 370Z uses a y-pipe, not an h-pipe. these nismo versions are meant to support the h-pipe. in fact, that's the only difference between the nismo and regular amuse exhausts. the flanges that mate to the midpipe are different.

but you gotta pay for the extra metal :p

they do have the regular 370Z versions available as well - R1 Extra, R1 Silent, R1000, and the R1 Progress.

...what, MIKE NO LINK TO THE PROGRESS?! :stirthepot:

Nope. You will need to buy the ones made for the non-Nismo Z. The pipes after the cats are different. The non-Nismo Z has a "Y" pipe (hence one pipe collector) the Nismo ones have a "H" pipe with two pipes coming out from the cats all the way till the muffler.

If you wanted these...then you would have to get a different front pipe that feeds into the mid pipes. Would not really be economically worth it at that point though IMO.

The non-Nismo versions are still cool. :tup:

Oh crap....Phelan beat me...now I feel like a repost LOL.

Question...

Why is it always shown on the cans that go = when they are burnt Ti, one side is always 'burned' more than the other? Is there some serious reason to it, or is it just how that particular metal reacted...

I would think with the whole dual concept symmetry would be exercised here as well... Or am I just overthinking this? Its just always made me :confused:

You know, I've noticed this too and always wondered the same thing, why is one side burned more than the other. I just figured it was part of the allure.:D

Just added it under the Extra. It's the same price as the Extra as well.

It's just about styling; nothing's restricting them from doing an even burn on each side.
I personally like the way it is right now, it's not "overly" symmetrical :tup:

Also, I just added to the above post, the y-pipe Amuse designed for the Nismo 370z.

I believe phelan had a dyno sheet somewhere. Maybe he can chime in with it.

NOTE: Look @ the after dyno graph (fuzzy as it is). Had a really weird blip at the end of the dyno run. The exhaust...wasn't tapering off yet...:icon14:. Also, not sure what the effect is, but I did modify the secondary piping from standard Amuse layout (see post below).

Still, conservative, we'll call +15hp, +8tq, per weather corrected numbers. In case you wanted to know, this was done on a Mustang dyno.

again, keep in mind i customized my exhaust to increase the sizing of the secondary pipes to support my future pipe dream of supercharging the VQ37...

(badum *kish*)

i might also get some improvements with the new y-pipe that came in but i won't get to see until i get home in two weeks...
