I've had RRE headers a few years now, and the car is running better than ever. At some point soon tho, I have to assume the 3rd cat will start to clog and fail due to age and especially since running headers.
So 2 questions,
1) what are symptoms of a failing 3rd cat?
2) I'm inclined to replace w/ OEM cat and pipe, but has anyone had good experience with a high-flow aftermarket 3rd cat? Do all cat-back systems delete the 3rd cat? I'm not interested in a 3rd cat delete.
