Have a 2007 just installed D&D slip ons, Sounds great but I'm now putting on the TFI to add a little more fuel and planning on completing the stage one later. But just the slipons made a lot of difference in the sound.
After reading so many topics on the "right sound" attempts on these newer bikes, I don't feel so bad riding my '90 springer 80" Evo with WELL used SE Slips.... potato potato potato potato.....
