I have a 06 grand prix and when i get on highway i get a smell but i still have full power. I have some shops tell me its the cat and some that tells me its not. is there anyway to test if the cat is bad or not.

its bad smelling like rotten food. but its only when i get on interstate.
Rotten eggs? Sulfur? That's a bad cat. They're good for like 150,000 miles, typically.
