Yes, Vance and Hines DO make the Screamin´ Eagle 16 guage pipes in question. They are in fact the equivalent to the V&H Big Shot Staggered. V&H quality and sound. A very nice product and will look and sound great on your ’06 FLSTNI. If after running those pipes a while, and you want a little more “growl” out of them, (to hell with the neighbors) remove the stock baffles and install “Thunder Monsters” in them from www.bigcitythunder.com , and no, I do not work for them. Thunder Monsters will increase and deepen the sound of the pipes and improve the performance of the bike. Hope this helps and enjoy your ’06 FLSTN.
