I am never on this site, but figure I would link to the other R1 forum where this guy is building a slash cut style exhaust for the 07-08 R1's.

Below is a link to my review.

EDIT-New Prototype is in testing right now. Justin figured out a way to not have the bolts on the outside of the muffler. I am excited to see what it looks like.

I believe he is going to offer the exhaust in 3 styles: Polished, ceramic coated black, and unfinished.
