My truck has 4 cats and 2 need to be replaced, and it will have to be smogged next year. The muffler shops I've been to want $500-600 to replace them.

Do I have to have all 4 of them or will it throw codes? Is there a way to have one pipe coming down with a cat to my flowmaster? Sometimes living in CA makes me feel like this
