Anyone running these on a FLHX?
I am considering the V and H, Python, or Bassani or maybe Samson as well. Anyone have any experience with any of these? Which are louder, best performing, match well with power tune duals (heat shields) etc..

 

Seeing how you want somebody to give you a rundown/critique on 4 different sets of fishtails, I seriously doubt you're going to get any one answer that you'll want to hear as nobody has all 4 sets in their garage and change them out every time that they go for a ride for comparisons. Go down to your nearest Dealer and look around to see what they have in their used inventory then start the bike up and listen. It may take awhile for you to do it this way but you'll have your answer first hand.

 

For fishtails, Samson sounds the best IMO. For quality of the pipes you listed, Bassani are the best IMO. Python are made by V&H, they are made as Drag Specialties house brand. They are a bit louder than their comparable V&H pipe intentionally. Being they are made by V&H I would not consider them as I am not a fan of V&H at all.
