Does any one have a street legal LSx swap in CA?

The headers are an issue, but only because any "performance" headers relocate/remove the cats. If you make headers that retain the "factory" LSx cat location (right by where the motor meets the trans, on either side) you should be OK with visual. Passing emissions won't be a problem.

Like everyone said, the CARB ruling says that a motor swap can only be legalized if the motor being swapped in is smog-legal in the car it came in, and is the same year or newer than the chassis.

Not entirely true. You can swap a motor from the same chassis (such as a honda getting a B16 instead of a D16) without needing a ref's approval. However, you can drop a motor from any car into a US chassis as long as you have the approval from your local referee, thereby getting a BAR sticker.
