excessive sulfur odor on 2007 model year Yaris

[azncharm]

Went to the dealer last month with TSB print-out and they ordered the part. No questions asked. Called me back after a week and replaced the catalytic converter in less than an hour. However, I can still smell it sometimes. Less often than usual but it still happens. Before, it usually occurs in the first 3 minutes when I start the car. Now it smells less often and when Im about 10 minutes driving. Still observing. If it doesn't go away completely I will go back to my dealer.
