Agh P0420

[TWP987]

Love the P0420 code! Get it every other day! The cat was replaced 2 years ago, sick on the mil and nasty old egg smell. Should I buy another new cat? Or just "modify" what's on there and get used to the mil? I know it's slowly plugging up choking my car. What do you guys think? I'm sure it happens to alot of us. Thanks!

Ha ha that's what I like to here. That mil will just stay on though won't it? Anyways some pretty crazy bends to give it a poke! Maybe my borla will shoot better flames on backfire! YES!:D

What are you doing to kill them so quickly? Running super rich?
