Confused between AAM axleback or Invidia Gemini catback for Nismo

My budget is no more than $1000 and sound is my priority. Just want a bit more rumble for the Nismo.

However, any extra HP in the process would be welcomed. Does anyone have either of these setups on their Nismo? If so, any dyno-proven HP gains and could you share some pics? And how are you liking the setup?

I've read that the Invida causes a HP loss in some cases. Is there any validity to this? It also doesn't have a flex section...is this a problem?

Thanks
