NPP Retrofit adjustable collars rattle
Just installed the Nakid Parts adjustable collars on my NPP mufflers. Installed them and set them so the valve flaps are just ¼ open, sound is perfect for me, but the problem is on one of the mufflers no matter where I set the collar except for fully closed, I get a rattling from that pipe. I just reset it for fully closed and no rattle. Anyone else have this situation?
