I contacted them about the pipes a couple weeks ago. He was nice enough to send some pics.
Here's an e-mail I received from them.
Hi Mike-
Attached are one picture of a SportClassic (2006 swingarm) with regular BoomTubes.
Second picture is a custom exhaust I made recently and will do more of in mid-September when I have a 2006 SportClassic in the shop for fitment purposes -- it's a Zoomie / FunnyCar style upswept version of the BoomTubes that are perfect for the 2006 swingarm itself. I did a set awhile back for a SoCal Ducati customizer for an upcoming customer project he is building. (M900 Monster with 2006 SportClassic swingarm) I'm sure when everyone sees them, they are going to get all excited.
The S2R1000 BoomTubes from the Monster would look on the 2007+ SportClassics. But the 2006 iteration needs something special to fill that swingarm shape. I'm going to update the above 2006 SportClassic via the one owner later this Fall as well to the Zoomie style exhaust.
