just added a power vision and FM air box to my 2012 King. I have B&E Superflow 2s that I ran previously on my 1996 King and they sounded good. On the 2012 they are pretty quiet. Is this due to the cats? Or, are Twin cams just quieter?

I think it's due to the catalytic convertor in the header. I just put Rush slip ons (2" baffles) on my 2012 Wide Glide - pretty quite. I removed the baffles and it sounds just right - but not crazy loud. I don't know if I'm losing power or not though.
