Hey guys I have a 08 Ultra and I have put on V/H true duals, Rinehart slip ons. I use to have Rush 3.5 slip ons and they were just too loud. Now I have a vibration and I can figure it out. All I did was switch the slip ons and now the floorboards vibrate so much they put my feet to sleep.

I have readjusted exhaust and tried everything I can think of. My next thing to do was place rubber grommets on the slip ons bolts and the transmission exhaust mount bracket to see if that helps.

My question is, has anyone done this and did they notice a difference?

If that does not work I’m going to have to put up with the noise and change the rush skip ons back
