02 Seville, 04 SRX (sold), 96 Eldorado (sold), 99 DeVille (sold)
I opened it up twice on the highway the other day and I could immediately smell it. Is this normal? I have an 02, is it possible that my CAT is a little clogged up? Its not throwing codes but I'm not sure if the CAT could be clogged without throwing codes.
