Trook, see my comment above, you cannot swap out a slip on with your already existing rinehart true dual system.

 

I thought I have seen 4" mufflers advertised that can be used with the factory Rinehart True Dual headers. Are you saying this is not possible? I certainly hope not!!!

 

I have the 4inchers on mine purchased recently and use the stock headers. All I can say is I love the sound and the quicker aceleration I feel with them over the stock pipes. 2009 Street Glide.

 

What I am saying is rinehart does not sell just a set that will work with thier headers. You buy the complete system, or you buy a set of slip ons and order a vance and hines true dual to go along with. The diameter of the Rinehart true duals is different than a stock slip on. I wanna say it is 2.25" vs 2" with a slip on. Gerrald Rinehart and I had a long convo about this at AZ bike week, wich is why I no longer run his 4" slip ons.

 

Call the DrVtwin they always seem to get a good price for all of us

 

i am not sure they are worth it yeah they are quieter but you will loose some backpressure in which case you will loose torque
according to rinehart they both put out the same DB but one is deeper then the other
I do have to say if they were available i would have but i like my bike just the way she is
just my 2 cents
