Best exhaust for maximizing the power of my Nissan 370Z?

I'm looking to upgrade my exhaust system on my Nissan 370Z and I'm wondering which setup would give me the best power gains without sacrificing too much sound. Any recommendations?

In my experience, the best exhaust system for maximizing power on a Nissan 370Z is the Motordyne Shockwave TDX2 Catback exhaust. It provides great power gains and an aggressive tone without being too loud.

I highly recommend the Invidia Gemini exhaust for the 370Z. It not only adds more power, but also has a nice deep tone that isn't too loud.
