I'm currently running a single 3" with a magnaflow cat + magnaflow 12198 at the back on my S50B32 M3. It is LOUD as hell but has a great tone, with no rasp. I'm looking for a center muffler to quite it down, and I've narrowed it down to the Borla XR1 series, specifically either the 40944 (Sportsman) or 40575 (Multi-Core Racing).
So what is the $100 difference in price about? Whats the difference in the mufflers? Which will be quieter? I assume the "Multi-Core Racing" will be (is this right?), but I'm wondering if its going to be "$100 quieter", so to speak...
