What is the best exhaust for a Nissan 370Z?

I am looking to upgrade my exhaust system on my Nissan 370Z and I'm not sure which brand or type to go with. Any recommendations?

I highly recommend the Invidia N1 exhaust for the Nissan 370Z. It offers a deep, aggressive sound and noticeable power gains.

I've had great experiences with the Borla exhaust on my 370Z. It has a nice balance between performance and sound.
