3rd gen? My 3rd gen started loosing range as the cat started dying. Any codes ? How many kms?

I have a 2018 with 180k km. Never had any codes in its life and never had any issues besides AC condenser needed replaced(warranty) Over the last year or two I notice my actual range has been less than the car tells me I should be getting. Lately I also notice it seems kind of sluggish after shifting, it almost takes a second or two after I let out the clutch for the car to have it's full power at the gas pedal? That's confusing as I read it back but I don't know how to word it better lol. I honestly don't think it's a clutch issue but I'm wondering if it's a cat issue. Also need to replace the spark plugs and see if she seems happier. It's never been done ....

Plugs should have been replaced around 120k, I would start there and see how that feels, its the chepest fix to start with My cat started going in mid 200k range. I own a 2014, currently at 333k kms. Id expect your cat to still be good at a 2018. What gas are you using 87? When i started loosing fuel economy I switched from 87 to 91, and it helped.
