I am fan of Wings exhausts for some time. I had them on all my KTM's and I decided to get one for my 1090. Craftsmanship and attention to detail is outstanding. Every can is a work of art. Minor downfall is that it is not CE approved, but that is not an issue where I live.
Wings for 1090 is much smaller that original silencer.
It is also much lighter. Wings weights only 2 kg. I couldn't measure the weight of stock silencer, as my little scale is limited to 5 kg and it is heavier than that.
Wings comes with very nice bracket and installation is a breeze.
Upper carbon fiber guard come as standard and lower carbon fiber heel guard is purchased separately.
Looking at the pictures, I realize that it looks much better "in person", it seems that my photo skills are limited. In my opinion, it is best looking exhaust can for 1090.
