If you'd spend 5 minutes searching, you'd find plenty of dyno-proven results all over the place.
The short answer is yes, you'll pick up your 18 CRANK horsepower at least, more than likely. But I would NEVER even imagine of installing the silly Nismo exhaust for a "performance" gain. So many better options out there...
