Most importantly I think you need to first confirm if the 2015 Nismo exhaust is "better" and / or louder. I can't imagine it is much different than every other Nismo exhaust out there just because someone else makes it, unless it is designed differently. Nissan would still have strict requirements for any manufacturer to produce the Nismo exhaust.
