I have a lightly used M8 DK Outlaw 606 high flow air cleaner and external breather kit for sale. The kit is complete with all hardware, back plate, back plate spacer, new gaskets, external breather bolts, external breather banjos, breather filter and the hoses I set up on my bike to run the external breather behind my exhaust and down to the frame where the yellow arrow is pointing to in the picture below. If you want to route it to a different spot you will need to buy more hose but it is super cheap.

I ran this set up for about 3000 miles before removing it. Paid $269 plus shipping for the kit. Asking $180 obo shipped within the CONUS only.
