Very quality product and one of the best looking exhausts for the 690 Duke (in my opinion). Quick and painless shipping by KTM Twins!
The only negative thing i have to say about it is that the pre-installed Decibel Killer in the outlet of the exhaust gives this muffler THE SAME EXACT SOUND as the stock exhaust. FYI: Akrapovic does not make it easy to get the DB Killer out (it does have an accessible allen key screw that holds the DB Killer in the exhaust, however, they put a spot weld so you cant take it out or even fit allen key in the head of the bolt. Had to drill out the rivets, take the end cap off and grind the head of the allen screw off to get the DB Killer out. As far as i could tell online, the older Akroapovic Slip-On did not have a weld holding the bolt in and the bolt could be removed without opening the exhaust). EXTREMELY happy with the sound after removing the DB Killer.
