    No, its actually the other way around. I have the riva through hull exhaust, and it doesnt line up right. This setup is for the stock exhaust setup. This is the reason im selling it.

    It lines up correctly for the stock exhaust setup. The j-pipe fits into the side without the bung hole.

    What kind of gains could one expect on a stock boat with the resonator in place? 50rpm or so? Then with the resonator removed a total of 100?

    Im not sure on exact numbers but, that would sound about right. The stock waterbox is very restrictive.
