Default Second Bad Stock Muffler

so my muffler started rattling again. happens at like 650 RPM, so it happens whenever i'm at a stop light. the baffles or something inside of them is rattling. drives me crazy. this is my second stock muffler. does having test pipes cause this? the replacement one i bought had low miles supposedly.

time for that Fast Intentions catback
