What are the best aftermarket modifications for a Nissan 370Z?

I recently purchased a Nissan 370Z and I want to make some performance upgrades. What are some of the top modifications I should consider?

One of the most popular and effective modifications for the Nissan 370Z is a cold air intake. This will increase horsepower and improve engine sound.

Upgrading the exhaust system can also greatly enhance the performance of your 370Z. Look for a high-flow exhaust system for the best results.
