I have for sale a 07 stock waterbox thats been modded (shortened and gutted) and a Riva Aluminum Thru Hull Exhaust Replacement Pipe both have around 60 hrs.
I'll sell both for $250.00 plus S/H in the states. I dont have pics of them yet but I can get some. Buyer would have to get the coupler and clamps for the connection of the pipe to the box. I would also be willing to part them both for $ 200.00 obo for the waterbox and $75 for the pipe. So I think that the combo is the way to go. Paypal accepted.
