also asked Akra if they have something in the pipe for the R3.. same reply: no
also asked many others, Zard ist the only company which made something.. and they now that they are the only ones, who made something nice looking.. and they get paid for it.
werkes, patriot what ever.. forget them, they are just straight stove pipes.. in my eyes with "no function" and the "design".. not worthy to be mounted to the R3 - sound? they are loud, nothing more - i expect more.. missing Euro5 homoligation is another show stopper for the "american" stove pipes.
