Does your MPE rattle during cold start or has the new clamp fixed that problem?
Also, do you happen to have the part number for the new clamp?
My dealer fixed the cold start rattle to some extent but there is still a tiny bit left. I would rather have them fix it with the new clamp. Not sure if it can be done to an existing cut in the exhaust as the new one is supposed to slide over. Thanks in advance!
