So when building my 959 Race bike I bought a Akrapovic kit. Went to fit and y piece was for 1299. So to get a 959 y piece I’ve had to buy a complete new kit. So for sale is some brand new exhausts, opened one box so you can see. Literally came into country from Italy this week. Comes with 1299 y piece (which has done few dyno runs until he thought was too too noisey) fitting kit and instructions with removable baffles. No map key, but when fitting these I’d run it on dyno and get set up properly. So £1850 posted or near offer
i doubt it sounds like he was in the same position as you and had to buy a new exhaust because these dont have the y piece and it sounds like they dont sell it seperately.
I’ve just brought a set from a guy in the US. You can by a link separately (£120). The 1299 cans have been stripped of its Cat and have been modified so I’m just waiting for delivery.
