Those are the them. I picked up a pre-owned SBK set recently. Build quality seems good and their website says several race teams use them but, I haven't checked.
The bracket attaches at the rear of the foot peg with the hoop pointing downwards. In the image u can see one hole next to the peg, this attaches to the hooped bracket at the higher fixing point allowing the exhaust to join the hoop section.
Hope that makes sense
