Most people would tell you to just turn it off in the tune with HPtuners as stated above. That’s what I would do.

I assume you’re not worried about your actual vehicle emissions or else you wouldn’t be driving a TBSS lol. You could buy a set of headers with a catted Y-pipe and technically “fix” the issue too. You’ll have a brand new set of cats, they just wouldn’t be factory cats. And it’s be less than $2500 too
