Exhaust is sold and en-route to the new owner.
To answer your questions though. The Nismo is rated 18 HP more than the standard Z which from what I have read is a combination of a light ECU tune and the exhaust. So HP gains for exhaust alone roughly would be 8-9 HP.
The sound I can't address because no one drives a 370 at the events I have been to all I have heard is 350 with aftermarket exhaust.
The main difference is the Nismo has a H pipe were the standard Z has a Y Pipe. I do think that the H pipe gives any future breather MODS you make better overall potential but, it would not be by a whole lot.
I wouldn't think the Millage would be affected.
