Here's another question... Which SC is the quietest in operation? Don't get me wrong, I understand no matter how you do it that seeking more horsepower will always result in more sound, but if I have the choice and all things being equal, I'd like the quietest SC I could get.

I partially ask because I was just watching youtube videos of the Sprintex installed on JK's, and the Sprintex seemed noticeably louder than than the Mag SC videos.
