A buddy of mine changed my mufflers to second hand Original Flow master 40s that I got on ebay (my preferred sound). Since the change I now have this repetitive vibration/rattle between 1800 - 2000 rpm when pulling away. As the mufflers are old and secondhand might this be a broken baffle or deflector?? Video with sound attached. As always, thank you for your thoughts/advice
