Although I like my 06 IS350, Im always concerned about expensive repairs--Nav screen going out, engine oil consumption, and replacing catalytic converters.

I had the car in the air yesterday and counted 4 cats? Im sure the dealer price for new cats is a rip off. I saw a lot on ebay--some say CA legal, some are not.


Any ideas??

In California, if you're replacing the converters it must be documented prior to the replacement that they are bad. Have you failed emissions already? From the reading I've done on the subject, the Cats aren't something you're legally allowed to mess with/install on your own thanks to CARB.


Here is a quick read of the FAQ's on replacement from the state: http://www.arb.ca.gov/msprog/aftermk...tallcatq&a.pdf

Here is a quick checklist of the requirements the installer must go through:
