www.preignitioncc.com/cust/viewHafcVideo.htm ================================== The PICC will NOT fly in California.You can only use state approved cats.These folks may sell you one,but without CARB approval its crying time at smog check.
In my case on a VW they check the serial number on the thing as part of the smog check,not sure how others are checked.
I ran into this when my cat failed and I was looking aftermarket,it was a no go for VW's but there are some approved for other vehicles.(Turned out it was actually a computer glitch factory repaired,saving hundreds!)
