When I purchased our 2007 ZX-6RR I had the dB eater shoot out of the after-market MIVV exhaust (mounted with a large circlip) on the highway at a legal 280 indicated speed (to check if all the power was there), that was fun too. Luckily nobody right behind me. Also the discussion afterward with the seller lol, where he swore it was in there when I left (he was right). With our 1997 CBR900RR I also lost the dB eater but at much more moderate speeds (fixed with 1 screw), I seem unlucky that way 🤷‍♂️
