Here is my amateur answer to your situation.First I have Rinehart True duels on an 07 Ultra.They look good and sound great,except for long rides,little too noisey then.My bike is still hot in city traffic,I have added heat shields and Freedom wings,both help alot.The noise police are really knocking at the door this time so paying $1500 to get a tickey don't make sense to me.Mileage is less I think.Trade in value is nil for the change down the road,because stock bikes return more of the investment.
If You want rumble,get slip ons and don't spend a fortune cause the "times they are a changing".:cry
