Guys i need some help. As of lately i am getting a very strong exhaust smell in my car. It happens while driving or whenever the engine is running. What could be the problem? thanks a lot

First thing I would do is check for any exhaust leaks.

I would say its your cat going bad.Does it smell like raw eggs?Does it reall smell foul?If it does than that would be my guess.
