Do you have a warranty on your catalytic converters? If I have it replaced now, and it doesn't pass smog in Sept. will you repair/replace?

Catalytics come with the manufacturer warranty, which obviously depends on the manufacturer. Mine came with 3 years or 36,000 miles, whichever comes first. I think Colby provides lifetime warranty on labor, but I'm not 100% certain.

And it would need to be tested and proven bad also. There are several systems in a car that can cause a car to fail smog.

They said as long as it's not to my negligence...
