Is it possible to buy or upgrade to a "Silent Stinger" exhaust plate if it did not come wiht one? I just purchased a 2017 Ri 257 and love the ride and size when we are not surfing to travel across the lake in comfort and style. Unfortunately the boat did not come with a "Silent Stinger" exhaust plate and it is louder and more fumes than I expected when surfing.
Also, anyone have favorite settings for surfing for the ballast and CATS?
Thanks
