What's the best exhaust system for a Toyota Supra?

I just purchased a Toyota Supra and I'm looking to upgrade the exhaust system. I've heard that the stock system is restrictive and doesn't sound as good as it could. What's the best aftermarket exhaust system for a Toyota Supra that will give me better performance and a more aggressive sound?

I've had great results with the HKS Hi-Power exhaust on my own Toyota Supra. It provides a deep, throaty sound and noticeable performance gains. Highly recommend it.

I would recommend the A'PEXi N1 Evolution R exhaust. It's a bit more aggressive sounding than the HKS, but still offers great performance improvements. Plus, it's not as expensive as some other options out there.

Avoid cheap, no-name exhausts as they may actually reduce performance and potentially damage your engine. Stick with trusted brands like HKS, A'PEXi, and Greddy.
