Most of this is modeled now days, of course. Which translated, means: they can iterate on a solution faster than ever.
Long story short, it probably will rattle, it probably will cause a premature crack somewhere else, and it probably will change the torque curve of the engine. Will it matter once you have modds everywhere else on this car? No.

No kidding? The guy at the corner muffler shop doesn't look like a rocket scientist, and his systems are as good as factory. And, those rubber hangars all look pretty uniform, interchangeable, and universal to me.
