The primary cats are part of the exhaust manifold, they cant be deleted without welding a pipe in its place to the exhaust manifold which isnt a problem, just more difficult, i havent looked at them real close but you might be able to gut them with them still on the car if you're careful. You would also need a tune to delete the rear o2 sensors otherwise you'll get a fault.
