Could BMW void the warranty the covers the engine and turbo because of an aftermarket exhaust?

A small number of authorized dealerships' service departments are in the business of selling/installing limited number of aftermarket "cat-back" exhaust systems. Was informed that cat-back system should be fine with the warranty as long as catalytic converter(s) is/are not removed and/or replaced. Any aftermarket pipes "before or the replacement" of catalytic converter(s) such as downpipe or catless downpipe will likely impact/void the factory warranty.
