I'm pretty sure I have a clogged cat. I'm going to try to confirm that this Friday. If it turns out to be the case has anyone ordered either of these from rock auto? There aren't very many choices so I'm hoping one of these will do. I have to get emissions tests when I get inspections so blasting a hole through the middle isn't a long term option. I don't live in California or any of the other states that have extra strict emissions.
