Probably a stupid question... but im looking around for an xt660r 2into1 exhaust system that doesn't go underneath the engine. But i mostly find ones that are for the xt660z ten' that are like this. Would this xt ten downpipes fit the xtr?

i say just the down pipes as i know that the frames on the two bike are different so the can mounting spots would be miles out. but if the both have the same engine then maybe the downpipes would be near dead on?

cheers
