Mine came with the cf remus cans.
Original size is here
for more detail.
When I wanted a refill because they were getting real loud, we discovered there's kind of a sock inside, to protect the cf from burning through. No refill possible without a Remus package, which they don't provide AFAIK. Then I found out a Bos silencer is the same size, so now they're all stainless.
They guy I turned to for the refill, DAM exhausts, told me his cf silencers are stainless inside, with a cf sleeve.
Cool looking bike you got there.
