Exhaust shutters will rattle at idle. If you have S.S. tips look in the tip from the back and see if they are the metal type internal flappers and the rubber has come off the edges? While idleing turn the wheel and see if it gets worse or better. If the tone changes pull the drive and check the gimble brg.

I was going to mention the same thing....the exhaust shutters...I have captains call in mine, and the shutters make a little bit of noise at idle....

In order to do that, you're gonna need a seven-sided gangly wrench.
