NISMO exhaust (not S-tune) on a base 370Z (sport)...

I wonder if you can find a used Nismo ECU and just replace the base model ECU. Anyone see problems with this?

Yea the problem is finding a used Nismo Ecu. If you do find one put me in for a group buy..

Nismo exhaust is only good for ~7hp over stock Z. The majority of the power comes from the tune. There isn't much difference between the stock exhaust and the Nismo. One week after I got my Nismo and swapped it out for my previous Z's FI 18' resonator with carbon fiber mufflers. There was a good noticeable gain on the butt dyno, not to mention a difference in sound and much lighter in weight. For me the Nismo was not much better than stock in the sound department. For a stock Z the Nismo exhaust is a good upgrade for those looking to not spend that much money but personally i think it's worth the extra money to go with aftermarket. My Nismo exhaust is just sitting in my garage for now.

So I'm totally reviving a thread from the dead, but the Nismo exhaust does sound noticeably nicer than the stock base exhaust. The best part is the sound doesn't drone or impede music/conversation in the way that some exhausts are prone to. The tone is much deeper and the car seems to rev a little freer in the upper rpm range. The tips are much nicer than stock as well, so you get an aesthetic benefit also.

The Nismo exhaust is good for people who want a little nicer sound and a little nicer output for a price lower than a new aftermarket system. It fits well also, you simply use two of the rear section brackets instead of three.
