Hi Imran, what's your point of view on the OPF deleters from Leib/Manhart? Do you think using these would still void your warranty or not? The car won't throw a CEL or go into limp mode, but I keep wondering if somehow BMW will still be able to tell that the OPF's have been tampered with (e.g. if the measured values would somehow indicate to BMW that something is not right). I would put the stock exhaust back on and remove the OPF deleters each time I take the car in for service.

Thanks in advance!
