"Count" Basie has/had very good sounding pipes/horns.

 

Yes off the charts for me.

At the moment leaning to the 3" Cobra going by a lot of different sound clips on lots of mufflers. Trouble is I know sound clips can be deceiving. My buddy has a Slim with V&H Twine slash 3" mufflers and they are just a little raspy for me, so that one is not on my list.

 

I once heard a set of rhineharts on an Ultra and was sold. Bought them for my bike, don't really like them.
Heard a set of Vance and Hines on one bike, sounded like fatty crap on another.

I hot swapped VH Big rad 2-1, rinehart slip ons, VH big rad 2-2 and then full on drag pipes.

The drag pipes sound the best to me.

 

Supertrapp. You can tune the sound to where you want it. I think they're the only mufflers you can do that to. I love mine.

 

A buddy I ride with has a 2008 Road King, he also has the Rineharts but are not nearly as loud as the one I had on the Slim S. (he was a little pissed about that?) He figures it is because the 110 pumps a little more air, therefor louder?

 

You should post some pictures of your setup! I think the Jekill exhaust system is some awesome tech. If i recall, they want like $3k for it, which is NUTZ!

 

Here it is, at least without the seat (Corbin has it for warranty work). I bought the exhaust from the Jekill & Hyde Booth at the Tradex Motorcycle show in Abbottsford BC. They were regular $2899 but the Canadian Rep had them for $2499. Trev Deeley in Vancouver BC wanted $3500 installed before taxes? They are really easy to install yourself!
