What is the best exhaust system for improving performance in my Toyota GR86?

I just bought a Toyota GR86 and I'm looking to improve its performance. I've heard that changing the exhaust system can make a big difference, but there are so many options out there. Which one do you recommend and why?

I've been a mechanic for 10 years and have worked on many Toyota GR86s. In my experience, the best exhaust system for improving performance is the Borla Cat-Back Exhaust. It's made from high-quality materials and has a straight-through design, which allows for maximum air flow and improved horsepower.

I love my Toyota GR86 and have tested out a few different exhaust systems. The one that has worked best for me is the Invidia N1 Cat-Back Exhaust. It's a bit on the louder side, but the deep rumble sound it produces is amazing. Plus, it has improved my car's acceleration and overall performance.

I recently upgraded to the HKS Hi-Power Spec-L Exhaust for my Toyota GR86 and it has made a huge difference in my car's performance. Not only does it add some extra horsepower, but it also has a sleek look and a great sound. I highly recommend it.
