Over the weekend I got a secondary cat delete I still have both of them I put it in my trunk but on Sunday I got a check engine or I noticed I had one and these are the codes it’s throwing up P0430, P0430 (again), P2098, and P0430 for the third time does anyone know why this is happening?
I apologize if the threat/post isn’t good I’m still getting the hang of the forums.

You have an exhaust leak, I’d guess. The secondary cats are not monitored so taking them out doesn’t cause any problems unless you cause an exhaust leak.

Agree. Car is very sensitive to exhaust leaks. Check all bolts for tightness and is there are any cracks are pin holes in welds.
