California requires that the cat converter be calif certified. I believe they are stamped CA CARB certified or something like that. And they are the more expensive ones. Perhaps if a smog shop sees a nice new one on there they will be inclined to check for that.
Exactly!
The CATs on many vehicles operated in CA are CA specific. Ours went out in our '89 Ford Class C 27' Ultra. Talk about LOSS OF POWER! It was like someone immediately hooked up the USS Midway to our rear bumper. Full throttle at about 5 mph. I had to search high and low for the specific CAT for that engine which, at that time, was a 460. Now, to the OP, nyny, I think I got ours at Ed Hansons Muffler. It's been suggested already. I know Ed personally and, without a doubt, one of the best exhaust techs there is.
He's got a rep for the highest quality work, this side of the U.S. He get's people, especially with Hot Rods, coming in from all over the state and, even out of state. He walks you though what's happening, and what's the best course of action, for your particular vehicle. That motorhome of ours, sounded like one of the cars in the movie "Bullit" when he was done with it. But, normal driving around was not intolerant. I'm not a noise fan so, he equipped it with the correct CAT and, the best possible TRUCK, flow-through muffler I could get.
It ran waaaaaay better after he was done with it. If you don't know where he's at, he's located on North Barcelona in Casa De Oro. (My old stomping ground). He, without a doubt, is the best place to get your issue resolved, while residing in CA.
Now, I'm not sure where you're heading or, leaving to when you leave this state but, there are some states out there that are right along side CA in their smog requirements. I don't follow all of them but, I've read that some are pretty restrictive too. You'll have to do your own research on that. Good luck.
