40 or Super 40?!

i am getting exhaust soon here and wanted to see what yall think woul dbe the better option? both very close i know but maybe one of you has heard them both

 

go with the original 40......sounds awesome, and i bet you really couldnt tell the two apart as far as sound goes.

 

Does anyone know what the difference from the 40 to the 44 series is?

 

i think the 44 may be a bit louder than the 40, but they are both 2 chamber mufflers though, so not too much of a difference.
