I'm sure the smog technician won't see unless he lifts it up. Where my dad goes, they just stick some tube thing into the exhaust tip, rev the engine a bunch, and it passes (atleast for my parents' cars lol). The two cats must be there because each one cleans the exhaust when it passes through on out to the tips (visible last part sticking out the back of car). If there are two independent exhaust pipes, then each has to have the exhaust cleaned by its own cat. An exception is that there is one pipe going from the engine, to a large cat, and two pipes coming out of it to the tip ends. Sorry for long reply, hope I helped.
