Just last night I installed my Scorpion cat back on my R53. It sounds excellent and the fitment was pretty good, aside from some missing bolts and mismatched screws for fitting the kit. My problem is that I did not adjust the hangers and the exhaust tips burnt my cutout in the bumper a bit , since they were making direct contact with it. I used my utility razor and neatly cleaned the edge of burnt plastic away from the tips and now it just slightly makes contact. Sometimes I can feel a vibration now and then when the car is running as the tips touch the bumper, however it is not burning it anymore. Can I leave this as it is now? or will it cause further problems in the future? Or should I remove the system in an attempt to bend the metal hangers?

Thanks in advance!
