Researching some exhaust options for a 950, and curios if anyone knows the difference (sound and performance) between the SC project S1 and SC1-M. I can't seem to find much information on the forum or web, but do like the looks of the SC1-M. I am trying to decide between an SC system with SC mid-pipe, or the Akra slip on's with arrow mid pipe. I like a good exhaust note, but also don't need the loudest system. I would leave any kind of db killer in place as well.
