Well spotted guys. The Spaghetti headers are for 851/888’s only. I’m sure Steve R or Ducatidad will be along soon to confirm. The high level 50mm silencers will fit 900ss/851/888’s I will put up a price later for the complete system. I’m a bit reticent selling the headers they are a work of art, I like the them just sitting on my garage shelf. Lol
I think the 'standard' 900ss headers are around the 40mm diameter mark where they meet the silencer, so possibly some work required to fit a 50mm silencer onto a std 900ss header. (I stand to be corrected).
