The BMW dealership installed the exhaust? Did they also install the CEL delete adapter and lambda adapters? The reason I ask is because I'm thinking of buying this exhaust and want it installed properly so I don't get CEL. I dont know if my dealership will install the exhaust. Even more so, I don't know if they know how and are willing to install those other components. Does this dealership have special experience in installing these exhausts? Also, does one need both the lambda adapter and CEL delete kit? Thanks.
