As far as catless goes, its a really good option. Please note it will throw a check engine light and a fuel smell due to the lack of cats

I have it. I liked the gradual taper to eliminate bottlenecking. Sounds a bit louder on startup and you can hear the turbo while driving. The smell from having the windows down while stopped is a little overpowering but I don’t mind. Definitely get a new gasket before installing. Don’t reuse the old one
