4 Cats, better emissions??? I am not referring to the new 4 cat systems on the Camaro, CTS-V, etc. With those, one is a light off cat to get the second working more quickly - same idea as the AIR system on our cars, lights the cats more quickly.
What I am proposing and asking for opinions about is using inline cats on both sides for a cleaner sniffer test. The idea would be to splice into the AIR tube and run a secondary into the second cat inline. With the AIR on, I believe the emissions would be improved, but once the car enters closed loop, would any effects remain?
