Are you sure your catalytic is still in good condition? If its been on the car since the beginning, then you may want to take it off and make sure its still packed with the stones and mesh etc. I took mine off to hollow it out since I am in NY and don't require testing- and to my surprise it was already hollow. The mesh that holds all the stones blew out from old age and the heat, causing all the little stones to get lodged in my muffler, I spent a good amount of time shaking them out, still not getting them all so I had to buy a new muffler. There was only a little piece of the mesh left in the catalytic. Anyway, if it has never been replaced, check it out, make sure everythings where its supposed to be.
