Nasty exhaust smell

[ChromoTech]

Lately my Pathfinder has been smelling like rotten eggs when i drive it at highway speeds :oops: :X

could my cat be clogged?

if so any ideas on how to solve this problem?

its the cat. when the cat goes bad it smells like rotten eggs. Change it. you might also find youll get a smoother running car if its all clogged and junk. or just take it off and take a metal rod and smash the screens out and have a hollowed out cat if you dont feel like spending the money for a new one. But I dont know if you need to pass a strict emissions test in your state or not. But here in MA you couldnt pass with a hollowed out cat converter.
