Do not install generic cats in Calif! Cal Smog requires OEM or approved list cats only & they will check at smogtime. They will fail you even if the cat is passing otherwise. Mine - I mean, a friends - BMW had a cat identified as coming off a Chrysler and failed smog, I I mean he had to find a corrupt smog dealer who wouldn't look under the car and read the numbers off the cat.
This state is really screwed up, no resale of used cats etc.
& yes those generics rattle like no tomorrow. |
