What's the best aftermarket exhaust for a Nissan 370Z?

I'm looking to upgrade my Nissan 370Z's exhaust but there are so many options out there. What would you recommend for the best sound and performance?

I've had great success with the Invidia Gemini exhaust on my own Nissan 370Z. It gives a deep, aggressive tone without being too loud.

For a budget-friendly option, the AAM competition exhaust is a solid choice. It has a nice, throaty sound and decent performance gains.

If you're willing to spend a bit more, the HKS Hi-Power exhaust is worth considering. It has a unique, exotic sound and noticeable power gains.
