My AL8 came with a (350mm) Delkevic carbon oval.
A quick check of ebay shows you can also get longer or shorter versions, but the one on mine has a fabulous sound without being offensive, looks great and has shown no signs of deteriation over 1500 summer miles (which obviously isn't saying alot
)
Hope you like the pic (from when my bike was clean) as I was pulling my hair out tying to post it - I use Imgur who seem to have redesigned their website in the last couple of weeks
