Now got the Aros Marmitte de-cat header pipes fitted. I've not had chance to ride it yet, but first impressions are that they are very light, at standstill noise doesn't seem much altered with stock baffles in and only slightly louder than before with the baffles out.
Very easy to fit and everything lined up and fitted without any problems or modification needed.
