I notice my 1994 honda civic b20 turbo has been running kind of sluggish so i looked around online and seen someone say the catalytic converter might be plug up, so i was wondering do i really need the catalytic converter? where i live the cops don't check for catalytic converter or do any testing

 

If you dont get smog tested than no, not really. I live in Florida and dont think Ive ever left a CAT on a car

 

IF you were to run a cat i'd run a 3in from a diesel truck. but other than that id just run straight pipe
