I'm just looking for a tad more growl from my baby =P

A simple reponse is preferred, yes or no... I dont care much for HFC or the like because I figure the piping diameter would not be a perfect match at the connecting points along the exhaust since most aftermarket exhaust parts are wider... also, I want to stay CARB legal.

What I really need to know is if the points where the mid-pipe meets the muffler the same on the Nismo as any other Z or if you would be able to install the stock muffler of a regular Z on a Nismo in other words?

You answer is in the posts above the one you just recently made. If you have a NISMO (like me), you have an H-Pipe setup. If you have a Base or Touring, you have a Y-Pipe. Most websites will allow you to specify what vehicle you have and offer you parts based on what you choose. You could always consult Exhaust Sound Clip Database or Exhaust QRG

The answer is yes.

The muffler shape on the NISMO 370Z is the same as it is on any other 370Z. I had a muffler replacement on my NISMO 370Z that was designed for a standard 370Z and it fit as expected. The only issue is there is a rubber connector for an exhaust hanger that's different. If you're looking at the car from back to front it's the one on the forward left side of the muffler.

Thank you daleks... I think you're the only one that understood my question =P

So you're saying any 370z muffler should link up to the the rest of the Nismo's exhaust without any issues besides the one you pointed out correct? Is the problem that the muffler has a connecter to a hanger that's in another location on the Nismo? So the Nismo's muffler is suspended slightly differently then? What did you do to remedy the issue?

Yes, the mid-pipe to muffler connection point is the same NISMO or otherwise. As for the hanger issue, the position is the same, but I believe the rubber spacer is a little different. In another thread someone mentioned just leaving that mount off, but you could try just going to the dealer and buying the standard rubber spacer. Also, I don't know what the real term is for the part; I'm just referring to the rubber piece that goes around the exhaust hanger and is then screwed to something under the body of the car. In the below picture it's the visible hanger on the left.

I didn't notice the issue until I was in the process of removing the muffler-only section. It turns out the rubber spacer rotated and the hanger was rubbing against the metal portion of the bracket that held the rubber in place. That explained the rattling at high RPM.

Gotcha... sounds like an easy fix, just swap it out with the same part from the regular 370. This was exactly what I needed to know... thanks! =D
