i had a rattle or 2 on ours...things that come to mind..
1,,,large weight on rear..mine had to come off for cat back
2,,my flowmaster catback pipe was 2 piece,,clamp is given..i lightly tighten them..noticed clamp would hit rear if pipe was shaking hard..
3,,which was the issue,,abs bracket to frame..1 of 2 bolts was missing ...i never had to touch abs so ?
mine too sounded like loose x pipe ,,only touching exhaust,i only banged on exhaust
