I noticed when I getting on the highway today, and I got on it the exhaust smelled really bad. Is everything ok or should I check something out?

 

What did it smell like? If it smelled like sulfer or rotten eggs, then it's usually the gas you bought that is causing the smell. That was more common in the years past in the US. Cat's usually clean up any engine oil burn off until the cat's become coated with the "oil debris" and cease to function properly.
