It’s time to take a listen to the best in-car audio from the Irwin Tools Night Race on another edition of NASCAR Race Hub’s "Radioactive."

Kasey Kahne is mad at his car, Denny Hamlin is mad at Kevin Harvick and Kyle Busch is not at all happy with his crew chief, Dave Rogers. It sounds like the feeling is mutual.
