Finally got some decent weather to install the new MK45's on the 2017RGS. Also put the db reducers in as well. They sound great compared to stock and just waiting on the K&N filter to show up via UPS today so I can flash the ecm with the SEPST. Should be able to get it on the road tomorrow before the rains show up but initial sound is great. Great to have new clamps and bolts from S&S and basically a simple install. Of course getting the mufflers lined up equally was the last bit of the process but they look great on the bike.
