The only thing that makes the eggy smell is faulty Cats brother, Are they the correct cats for the car or just universals? Wrong parts do get installed unoticed sometimes, Unless someone is pouring sulfer in gas tank I dont know what to tell you.

Running too rich can overheat/overwork the cats causing stinkage.
