    riva exhaust question

    Just got my 06 rxp! I really want to do the riva thru hull exhaust. Can I just run that with the opas block offs and have the ski run fine?? Or will it lean out on me? Also does this exhaust void warrenty? I plan on more mods down the road, but for now thats all I want to do.

    thanks guys! That riva exhuast sounds mean!

    burns holes?!?! eek that not good! DOes the RR have the water injection? I" think I"m gonna do riva stage 1 with an exhaust. But now you got me questioning what exhaust to run!

    do those open element filters sit in a area where water wont get to them much?? I dont want to have to worry about injesting water!

    I've had the Riva exhaust since late last summer with zero problems, fyi I was running basically a Riva S.1 with it. Cant beat the sound when cruising when the backpressure builds up around 3k.

    The RR sounds awesome!! when you modify the waterbox with it.

    Ron, I hope u didn't get too much water in there I raced a guy in miami,that had a high temp warning, and he melted that pipe completely Needless to say I towed it back before it sunk. You definately need metal pipes to protect your investment

    That would be the RR one!
