I just installed the AFE full catback and it has a valve that utilizes the factory valve motor, you just take the little motor off the stock muffler and fit it in the new one.

Now every time I cold start it I hear a rattle on the rear driver side around the muffler but couldn't figure out what was causing it. It goes away after 20 or so seconds. Now that I'm reading this I believe it to be something associated with the valve. A cotter pin-looking piece of metal connects the motor to the valve itself.

That could be be culprit. Maybe when installed from the factory it's in there nice and tight but if then done again later on it isn't replaced perfectly. I will investigate tomorrow morning at start up.
