    Exhausting modding?

    I am installing a Riva Waterbox in my 2009 RXP and want to know the length to cut off the exhaust tip that slides into the waterbox that is clamped to the exhaust manifold. What size to drill the holes to let the water flow through the tip better?

    No need to cut or drill anything on the mid pipe.

    I am running the 2009 exhaust, I aint using the J-Pipe.

    Yes I am talking about the mid pipe, I use to run the older exhaust system with the J-Pipe an I use to cut an drill them for better cooling.

    There's no modification needed on the 08+ midpipe setup
