    Follow the template exactly when cutting the actual hole,put tape on the area your gonna cut,some also reverse the hole saw to score up the gel-coat before cutting into it.use the exhaust tip as a template when drilling the 4 mounting holes,NOT the paper template..

    Great advice by snoman.

    Here's a link to the instructions if you want to look over them
    http://www.rivaracing.com/instructio...5050_1_215.pdf

    The exhaust can be ordered in the forums online store

    If your installing the opas block offs at the same time, leave the left one off to allow access to get in through there to do the hose clamp up on the exhaust coupler.

    So that you can get the resonator out. I never do this step I just take a sawzall and cut off the piece of the resonator that the exhaust hoses connect to and then you can take it right out.

    Don't let it intimidate you. It's not that bad of a job. The exhaust sounds great!

    I'm just about to install the riva thru hull exhaust in my 2011 rxpx, The manual says to block off the water fitting in the pipe. Why? If I run water thru that location will it quiet the exhaust?

    Any water added after waterbox should quit down the exhaust tone some.
    So if the OEM setup has water routed to that location you can route to riva pipe with no affects.

    If you going with riva water box there is no where to add water so you will either block off water or route thru Hull fitting.
