I'm taking delivery of my G05 arctic grey M sport 30d this Saturday (upgrading from F15).
So far I've ordered the Shadow Line Exhaust Trims and the Performance CF Rear Diffuser. I'm sure the exhaust trims will have to be installed by the BMW dealership, but I'm wondering about the diffuser install difficulty.
Any G05 owner here that already have this diffuser installed? Is it easy to install? Or will I need to leave it to my BMW dealership to install it and hurt my wallet for it?
