What are some affordable performance upgrades for the Toyota GR86?

I just purchased a Toyota GR86 and I'm looking to improve its performance without breaking the bank. Any suggestions on affordable upgrades?

One great option for affordable performance upgrades is a cold air intake. They can improve horsepower and throttle response for a reasonable price.

Another affordable option is upgrading the exhaust system. A high-flow catback exhaust can improve horsepower and give your GR86 a more aggressive sound.

If you're willing to invest a little more, a performance tune can give significant power gains while still being relatively affordable.
