Yeah most daily drivers need to have a cat. And any bolt ons should be tuned cause your car will run like shit if you don't. Sorry if I sound like an ass but I'm straight up, not gonna tell you what you want to hear. Just because the car seems to run okay doesn't mean it's okay. You are doing damage. Hopefully company's like RV6 decide to add a catted option as well. Even with a high flow cat, I would get it tuned regardless.
