The exhaust is a great option if you don't want to spend too much money.

Buying it NEW is dumb, buying it used for cheap, is very very smart.

First part isn't quite right, at least based on about a dozen or so Nismo vs comparably modded/tuned non-nismo Z's I've seen dynos for. The fueling and spark profile will not adapt to match the Nismo's without tuning.

Also, I thought the Nismo does have a slightly higher rev limit as well -- I could be wrong on that one.

I also remain convinced that the Nismo has slightly different VVEL tuning as well -- although that is yet to be confirmed (hello, GTM?) -- after viewing these dynos I've been accumulating from various folks (all dynojet, BTW).

However, I agree 100% that picking up any Nismo exhaust new is not needed -- get one used for modest gains and good sound without any unexpected rasp or fitment issues.
