Best exhaust for increasing horsepower on GR86

I just got a Toyota GR86 and I'm looking to increase its horsepower. I've been reading about different exhaust options but I'm not sure which one would be the best for my car. What exhaust would you recommend for increasing horsepower on a GR86?

I personally have the HKS Legamax Premium exhaust on my GR86 and it has definitely made a noticeable difference in horsepower. Other popular options I've seen among GR86 owners are the Tomei Expreme Ti and the Perrin Performance exhausts. I suggest doing some research and deciding which one fits your budget and desired sound the best.

I've been through multiple exhausts on my GR86 and the one that gave me the biggest increase in horsepower is the AWE Touring Exhaust. However, it may be a bit too loud for some people's taste. If you're looking for a more mild option, the Borla S-Type is a great choice.

When it comes to increasing horsepower on the GR86, a cat-back exhaust is definitely the way to go. I recommend the Invidia R400 or the Tanabe Concept G Blue for the biggest gains. Keep in mind that these exhausts will also make your car louder and may cause drone at high speeds.
