2. after turning off the car, the back exhaust/muffler system is loudly tinkling for several minutes before it cools. sounds as if little metal bugs are hopping around in there, but it's probably just the sound of the hot metal cooling. still, does that suggest a problem?

My '03 does both also and noise #1 only happen on a cold start and for 1 second, it sounds like when the syncho on a manual tranny is bad and you try to shift it into gear (gear grinding noise). It's probably something to do with starter and I've tiptronic. Should we be concern?
