Okay, the Nismo exhaust is an H or dual exhaust system. It is not bad but it is not 2.5" all the way through. FI is an X pipe system, both of these systems have pluses and minuses but are much better than the Nismo exhaust system. You don't have to get a tune with any of them as the ECU will learn and make adjustments. A tune will benefit you in other areas like throttle response and maximizing your performance, but I would wait until you add a cold air intake and test pipes or HFC. Don't over think it right now because you only have so much money for mods. Get the parts first and then get a tune.
