Hi, I've searched through the forum, but not found any comparisons between the 2 into 1 hi-level systems from 
        
Off the Road and 
        
Metal Mule.
         
        
 I'm especially interested in the difference in sound levels, since I'm not so keen on having a loud motorcycle.
        
 I've read some comments about the Metal Mule system being too loud, so I'm wondering if the OTR system is quieter or not.
         
        
 Regards
