Which aftermarket exhaust system is best for my Toyota GR86?

I am struggling to decide between the different aftermarket exhaust systems available for my Toyota GR86. I want to increase the car's performance and add a deeper, more aggressive sound, but I don't know which brand or type of exhaust to choose. Can anyone provide some advice on which exhaust will give me the best results for my GR86?

I would highly recommend the Borla exhaust system for your GR86. It adds a nice growl to the exhaust note and has been proven to increase performance.

Based on my experience, the Invidia dual N1 exhaust is the way to go. It gives a throatier sound and noticeable power gains.

I have personally tried the Tomei single exit exhaust and it completely transformed the sound of my GR86. It also improved the power delivery throughout the rev range.
