If you are modded and the tune wasnt adjusted correctly and you are running lean you could have over heated the cats and damaged them.

You know there are a few other owners on here with similar set ups. Im going to revert back to stock andvtake her in for an exam at the dealer. If this does turn out to be a case of my mods without a tune doing damage somehow...im certain a few of you would like a heads up. I hope it is something unrelated because a love these simple mods (cai and ported tb) because the do just enough to make the car a little more aggressive. Smooth launches with improved tip in. The little exta umf from the CAI and much better SC whine! Im gonna be super bummed if they are the culprit.
