Shusher vs Nelson muffler on a 7 hp 702 Wheel Horse

[Lane Ranger 11,395]

I have a 702 Wheel Horse with a rebuilt 7HP Kohler motor that I have had a Shusher muffler on for several years.   
 

I was asked to test the sound of both by a Red Square member which I have done on some videos.   I did not test sound levels with equipment but you can hear both of them in lower level throttle vs higher throttle for yourself.  
 

These shorter mufflers have exhaust ports on both ends and they each have an internal baffle.  Similar in size.  So see what you think about them. 

The Shusher is in the second video and the Nelson in the third and fourth video.

Though the throatiness is different the level of noise seems nearly identical.  Am I right of do my ears deceive me?

Very close noise level in my opinion although the Nelson is a bit deeper in overall tone or as you indicate throatiness! 
 

The lower tone is  won by the Shusher !
