I'm thinking part of the rattle I've had lately is a cat going bad, I think this for 2 reasons. 1st is that the rattle only happens when I accelerate and ONLY when I accelerate after the engine and exhaust is at full operating temperature. 2nd is that when I give her the full enchilada (I prefer to call myself a "spirited driver" lol) I start to smell a rotten egg smell, and both of the top techs I work with and even an exhaust shop have told me that's likely a cat going bad.
I'm not too far up the road from you, just in Duluth. I'll be pulling the motor fairly soon.
