Post cat converter

Do cat conveterrs decrease performance (even more!) when they get old. Should they be replaces after 120K miles?

Thanks

Everything I've read says yes cats do rob you of performance as they get older. This happens because the cat gets "clogged" with the exhaust byproducts that it is filtering out. You can replace them but they are very expensive, try finding John Walker or Wayne on the posts and ask them, they are just 2 of the many people that have more information than me and are willing to help. Good luck, are you trying to pass smog test or just looking for a boost in power?
