Hello, I'm new here and interested in getting a GR yaris but I've got a few questions and found this subreddit and thought to drop them.

What is the difference between the GR yaris and GR yaris RS? I assume the rs is like the standard yaris with the body of the GR. Correct me if I'm wrong of course.

Which one would be better though?

And in the future, or at least once I buy the car, I would love to install HKS exhaust on it so which ones are compatible with each car?

I'm quite new to all this and google has all kinds of different answers which leaves me unsure with my decisions.
