You're sacred an air filter is going to void warranty yet you want to remove the resonator? Lol
Op, get an air filter, if you're really scared swap it to stock when you go in, it take a few minutes. As for exhaust, they font mind axle back. However if you're really worried, get the bmw performance exhaust, its expensive though.
