Looking at LRS and I see lots of measurements but no real comparison or differences to these 2. Can someone please explain the difference...I am brand new owner 2019 RG Special , 100 miles on new bike and DAMN love the ride, but can`t hear the radio at speed with stock exhaust. Just ordered Rinehart 4.5 slip ons and imagine it will get worse so wondering if a Screen change is in order....Please educate. Humbly Vince!!!!
