This will help you. In this thread OP installed the tips and he lost One.I have the same tips installed on my 2019 50i around same time.It's a perfect fit and look very aggressive. After reading OP lost One of his tips, I drilled small hole through all tips including the one on SAV to secure them with small screw. They don't rattle and don't move.Problem solved.
