0-300 miles no problems

After 300 I started to get the rattle my first batch had and it seemed to increase when going uphill.

After about 380 that rattle started go away and a bigger rattle came in its place (sounds like metal banging on metal)

Can anyone give me some insight if this is correct. From what I can remember my first batch of art pipes didn't rattle as bad as these are.

Current Mileage about 400
