I have been looking around for bumpers. So far here is what I found.1. Half cut shop original M5 front and back with fog lights. RM35002. M5, Taiwan PP material, front and back with fog lights, plus trunk spoiler. RM1500Is the original worth getting? In terms of durability, PP material should be good right? Does it look different after installing? Not sure if the RM2000 worth spending.I actually prefers Msport with 1 tail pipe. For M5 rear bumper, need to install another fake tail pipe. Anyone knows where can I install the fake tail pipe?
