         Yes. More volume of silencing material means a quieter exhaust. Also the greater cross-sectional area of the combined outlets means the pressure pulse is reduced (which is what causes the main difficulties in silencing a single).

              any single exhausts available which aren't loud, too expensive and OEM panniers fit?

         Yes. Have a look at the various Exan single can systems. They start at very similar prices to the MTC for a round stainless version. Mine is pretty quiet with the baffle in, not far off baffled Leos or Akrapovic (which I had before) - a nice sound, but still polite.
         
         
        
 
         
         Buy from 
        
Mad4Exhausts.com, not the UK importers, as they are considerable cheaper shipped from Italy to the UK privately.
