As earlier posted the part number is Vance and Hines PN 21905 and you have to order 2 of them (one for each side).
I ordered mine today, should be here in a week.
I ordered them mostly for looks, don't want it much louder and I have other toys for speed.
Please keep us posted with the installation and results
