Gibson 4" Quiet Tip
Definitely naked ear audibly quieter, like cover your ears uncover your ears, not that extreme but, point is, you can hear a difference, not an advertisement gimmick. i bought two , for my rzr 900s with the Gibson Stainless dual kit exhaust i already had installed, and it took away most of the popping and cracking sounds but still has the cool sounding idle and lows sounds, but definitely removed all my DCNR attention getting sounds 👍🤣, i liked to make noise but not if your gonna draw the wrong people's attention, specially if their not someone you want to talk to at that time or get parked for someother reason
