I'm looking at a 4Runner that is for sale in CA. What are the crazy things about CA emissions that I want to look at before buying a CA 4Runner? Yes, I plan to bring it to CO and keep it as my baby...
Removing the cat won't cause the check engine light to turn on but it will fail visual inspection and faill emissions. removing other stuff like exhaust manifolds and replacing them with non smog legal headers would cause the check engine light possibly come on or blocked, clogged, or bypassed egr valves and so onIts true, it is the owners responsibilities to get the vehicle smogged before sale. I bought my 4Runner from a guy down in Hemet. He smogged it 4 days before I got it. It passed, then I had to turn around and smog it again. GAG!!! Glad Im from Oregon though. Right now Im running straight pipe into a 2" cherry bomb. No muffler or Cat and nope, my check engine light aint on either. Good luck on your hunt for the 4Runner.
