I bought a set for my Z800 ex eps. Haven't installed them yet, but they look to be quality pipes. They come Black, pretty heavy duty thick plastic. Slide the pipes together and glue, silicone at certain junctions. Set of 4 pipes.....Air intake, CVT inlet, CVT outlet, and 5 vent lines (Front Diff, Rear Diff, Gas tank, Both front head lights.
Bought mine to get the clean air inlet above the normal dust cloud height. Did not buy it for deep water, although it should keep water out if you water proof it.
