The minor horsepower gain that a cat delete would cause, is the same gain you get when it gets cold outside.

Not only that but catalayic converters, being emissions and not performance based, have their own warranty mandated by the government.
you statement forgets that A/F can be altered via having no cats on the car. Will it? prob not, but BMW can say it will and good luck proving them wrong. And it's not the same gain as when it's cold outside, little different. Yes, federal emissions equipment has it's onw warranty but it is also ILLEGAL to remove and grounds for a warranty denial immediately.

the problem is if you remove the cats w/ are emissions equipment, then yesm the dealer can void the warranty. Most new cars are sold w/ this as a disclaimer. Yes, MAYBE you will win in court, but who has time for all that bullshit. Especially when removing the cats, BMW can easily say that the A/F ratio is now manipulated and yada yada yada your warranty is void. IMO not worth it for them to void a warranty on a new car. And yes I know all about the act, but you keep preaching about it, and it's not that simple as you make it sound
