RR & XR
I have both now, a 2015 RR and a 2017 XR, I am waiting for the 2019 RR to come in September.
I'm still torn on whether to put the full Akrapovic system on from my RR on to my XR, I have an HP can on there now and it's a nice sound without being too loud, but I would like to liberate the extra horses with a full system.
My Akra dealer says the RR system will not fit, but I think it's just the mid pipe that I need, the header and collector looks the same to me.
I'll probably sell the RR system when the time comes to trade my 15 for the 19, it's a full titanium evo system, so it would be a shame to break it in half and it's worth more to sell complete than the cost of an XR header/collector (stainless steel).
