Hi Jlabro.
I have Remus headers with a Carbon Bos end can and they are fine together, a good fit and look good. I have also just polished the Remus headers, plenty of wet and dry and a hell of a lot of elbow grease, but they now look great. I did 150 miles last Sunday and the headers have not gone back to their usual brown colour. A splash of wonder wheels after the ride keeps them looking great.
Hope this has been some help.
