A strange coincidence; was talking to a chap in Moto Corsa who has just bought an RS (he hasn't got on here yet as didn't want to scare himself), he had seen this and we watched this video in the shop. Apparently, this Ixil pipe is for a Yam R6 (and something else) so you'd need to find someone to make you the appropriate link pipe.
