Man, this company makes quality exhausts but finding information on them or even purchasing them can be a challenge. Anyone have an Arata S/O on your 1198 and what are you doing for an ECU? I can't find anything for the 1198, just 848/1098/1098S.
Dan Kyle is the us importer I think. You might want to talk to him. They never offered a slipon kit just a full system for the 848/1098. Nothing but promises and no delivery as of yet. They do make great exhaust though.
