We are very aware of that fact. We're in Kali. That is also a fact. At one time there were 49-state vehicles and there were Calif. only vehicles that were optioned with EGR, AIR, etc. that 49-state vehicles were free of. Maybe that Sub was originally a 49-state vehicle (?).

The big question is why the cat is where it is since the cats normally require heat shielding and heat of 600-800 degrees to work. Even Calif. doesn't require cats on old cars with new engine swaps because the old cars didn't have heat shielding under the pass. area.
