What is the best exhaust option for a Nissan 370Z?

I recently purchased a Nissan 370Z and I've been looking to upgrade the exhaust system. As a big car enthusiast, I want to make sure I make the right choice. Any suggestions?

I had a Nissan 370Z for years and I highly recommend the Stillen exhaust system. It adds a nice growl to the car without being too loud.

I've had good experiences with the Borla exhaust on my Nissan 370Z. It gives the car a nice deep tone.
