Suprised you got a police bike that did not already have pipes but some times the world suprises me. As for the choices, the 06 is old enough to get the old stlye SE pipes. The Rush are a similar baffel but offer different sizes so you can dial in the sound a little more. Rush and SE both have tip options so I would probably narrow it down to those two. Not tha familiar with the Bassani pipes other than seeing a couple here and there. that curvy back pipe does look cool though.
