Excellent pipes!
I just had a set of MK45s installed on my 2014 FLHTCU. I noticed the difference right away. The craftsmanship is impeccable, the sound is rich and deep, and they look great. I should have done this a long time ago.

Great mufflers! Nice deep sound
I have a 2014 FLHTK, I've been running CVO slip-ons for about a year. I was looking for a little more performance and a deeper sound. The MK45s are perfect. A nice deep sound with being annoying. I can hear the stereo over the exhaust when cruising down the highway and they have nice sound when you roll on the throttle.
