    Help locating the resonator on a 09 rxt is and install?

    I'm a car Mechanic by trade so replacing the parts is not a problem. I just wanted to know where is the resonator located? I know is at the back with this big black box. I can't see anything unless i move the stupid suspension on the IS. I will be getting the Riva kit RS16090. Is there a short cut to remove this? I took it to the dealership and they said the resonator has a hole in it. I just wanted to verify that is 100 percent the problem before i start taking this shit apart. The seadoo sunked. I got all the water out of the engine and the engine started fine. Luckily the engine didn't seize. I watched a video on youtube and i already know how to lift up the is suspension hull. Is it possible to cut the resonator and slide it out? I will be putting a 90 degree bend hose from riva. Let me know if someone can help me. Thanx.

    the resonator is a plastic muffler between the waterbox (first muffler) and the thru hull exit
    I bet cutting it up would be the easiest way to get it out (it was on my 13)
    if the resonator melted you must had a water shortage
    check for debris in the water pick up
    also check all exhaust hoses for heat damage
    if one of the hoses comes off or leaks you can sink again

    Thank you. Is it located on the left or on the right side? So removing 1 of the rear tray i should be able to access and cut it off?

    resonator is on right side next to fuse box, you can remove the battery and the fuse box bracket and if you can reach around to the front of resonator with a 10mm socket you may be able to remove the bolt that holds it down to the hull, if not you will have to raise rear of suspension to get to that bolt.Then pull it out though that compartment, Its a tight fit but I installed mine on my rxt-is through there.


    I have the riva rear exit exhaust with the rear bucket for (IS) ski's in classifieds if interested, They dont get the loud drone like the resonator bypass does

    So are you saying that this is better? RS15100-2
    RS15090-RSB . Which one is better? So the rs16090 is the same as the rs15090?
