This system was removed from my then 2006 K1200r, replaced with Akrapovic, I forgot I still had it, found it in the garage loft! These were made to fit all the K12 and K13 models R, S and GT.
Downpipes are in reasonable nick, I believe they are titanium!? They are very light, I think there is a hole where it goes 4 into 2, so will need a little 'tig'.
The end can is not so light as it contains the cat, its in good nick, there is some grounding shown in the piccy, you won't believe how far you could chuck them buggers over.
I'm struggling to come up with a price? A ton?
