How to upgrade the exhaust system on a Toyota Supra?

I want to improve the performance and sound of my Toyota Supra's exhaust system. What are some recommended aftermarket options and what should I consider when making this upgrade?

One option is to go with a full exhaust system, which includes headers, mid-pipes, and cat-back exhaust. This will give you the best performance gains and a more aggressive sound.

If you're on a budget, you can also just upgrade the muffler for a more noticeable sound. However, this will not provide as much performance improvement.

Another factor to consider is the material of the exhaust system. Stainless steel is stronger and more resistant to corrosion, while titanium is lightweight and has a unique tone.
