secondary cats don't require any mods to O2 sensors. They are only on the primary cats

so all of these exhaust systems delete only the secondary cats and not the the primary ones?

some delete the primary too. You either need a tune to get rid of CEL code, but then you won't pass inspection. Fabspeed is one company offering a HFC that won't throw a CEL code. Akrapovic sells their system with Lambda adapters to avoid a code - but they don't work and you still get a code (as of now).

I just added pics to the last page of that secondary cat delete thread so you can see what it looks like.

Yeah, there are only O2's before and after the primary cat. None after the secondary.
