For those of you wanting a Surf pipe you have the option to goto Fresh Air Exhaust and get one for your boat.

I had one of my 08 when the FAE was a new idea, then the very first one for a Mojo I did the mark up for FAE to build it on my 13-

Great product and I am pretty sure that they were some of the first to make them before the dealers started to OEM them.
