Can't go wrong with either system.
If you want quiet unti WOT go Borla 112, if you want a little noiser, go Magnaflow or Borla 125 (but the 5 inch tips look like carpola IMO)...
My advice is to find someone in your area with both systems and go for a ride. I had the Borla 4 muffler systemer (140112), and just took out the rear muffler's (like the 140125 system only with the 3.5 tips), and am finally happy with it...
The Borla 3.5 tips are the best looking out there I think.
