Well, due to an accident I had to replace my damaged 3.5” Rineharts for the new 4” (in Europe there was no supplier that could deliver the 3.5” anymore). So after searching this forum for any difference in sound I got a little nervous. I do like the 3.5 Rinehart sound and on this forum I read that the 4” is deeper and not as loud as the 3.5”. Well after my first trial today I could seriously not hear any difference. When pulling the trigger the 4” Rineharts are barking like my 3.5” did. Even as crispy.

My setup is a 07SG, stage 1 with V&H dresser duals, AN big sucker and 4” Rinehart slip-ons. Couldn’t be happier, because the looks of the 4” are better, definately with my stretched saddlebags.

Oh and duals are way more better than the standard head pipes regardibg to sound. Definately worth the pennies, if you are wondering and doubting for TD’s.
