Found this, looks like BOS used to make an undertail exhaust system that looked pretty good for this bike, but can't find it now on their site. But can find a pic. at www.probikes.nl you have to navigate through the site a bit to find it. but (on the left side) it's under the uitlaatsystemen (exhaust systems) BOS dempers (BOS mufflers) Honda then at the bottom of page 2 (use the > button up top) click on the "seatpipes" twice to see the pic.
Not cheap at almost 2,000 euro.

 

Here is another pic of this exhaust system.

Is that real...it looks modified graphically.

 

either way it looks pretty sweet..i dont think ive seen an undertail exhaust setup like that for the 929.
