Rotten Egg Smell from exhaust


Just had my oil cooler replaced from and oil leak i was experiencing. Now when i drive the car i can smell exhaust more prominantly than i could before the warranty work, and when i park the car, i can smell a rotten egg smell. I tried searching the threads because i have read about others experiencing this as well, but could not find the posts. Any information anyone has would be greatly appreciated. I am thinking i have an exhaust leak, but would that cause a rotten egg smell? Please help!

If the exhaust leak is forward of the cats it will have a rotten egg smell. That smell is exactly why I am not a fan of running without cats.
