How can i tell if it is my cats or pre-cats that occationally make my car smell like rotin eggs. It does not happen all the time and I cannot notice any performance diff. but annoying still to say the least, people have actually pulled up next to me and were like wtf, gag!!

I used to get that all the time under heavy acceleration.. ever since putting on an aftermarket y-pipe, I don't get it anymore.
