i think your best bet is to contact the seller of the ixil cans and request a couple of pictures of the underside / centre stand area. the r1 cans in the link above are no good, they are the wrong way round!
when time and finds allow i'm planning on buying 2 sets of (scrap?) downpipes and cutting them both parallel to and behind the exup assembly. then cut the two offcuts in unequal halves down the centre either side of the rear mounting lug, then one can be turned 180 degrees and welded to the other then weld the lot back to the downpipes. a custom link pipe would have to be bent for the nearside of the bike and an akrapovic purchased for that side too. (as i have an akrapovic already)
it's a similar plan for the pillion hangers, buy 2 hangers, cut the can mount from the off side hanger and weld it to the near side hanger, finish with paint or powder coat. that way it's a factory looking twin pipe system.
i have already welded bobbin mounts to my swing arm in preparation for the possible loss of my centre stand, although i'm hoping it can be retained...
helpful?
