I need quiet mufflers!

yeah, i used to let my neighbors just deal with it when i lived in california but now i live in england i have to warm my car up for 10 minutes before i can see out the windshield and i also leave for work at 5:45 in the morning. I don't know, maybe ive gone soft.
 
I don't understand how the MAC's are the loudest muffler on that list. Is there another brand other than the flowpaths they are referring to? I always thought the Flowpaths were one of the quieter mufflers compared to a lot of the Flowmasters and such out there. Maybe I'm just missing something?
