    Loudest Possible Exhuast Option RXP

    Just installed a thru the hull Riva Exhaust kit. Sounds better but wish it was louder!

    If I buy the riva water box will it be that much louder and worth me spending another $300??

    Here is a short video of idle with my TDR and Riva through hull setup.

    I don't think it is that loud at all. When my brother in law is following me close, he says it is loud as hell………..

    I picked up a used TDR waterbox for 150$ my rxp sounds like a mini offshore boat going about 40mph and idles loud enough to grab peoples attention. TDR is about as loud as you can possibly get it, seriously the best money ive ever spent. youll have to cut 1" - 1.5" off your J pipe to make it fit properly into the waterbox and there is also a pisser line thats in the stock system that can either be removed at the T junction right under the J pipe by just adding a straight through hose connector or it can be capped or fed through a pisser fitting out of the hull but i recommend just removing it. You will also have to remove OPAS (which makes the ski handle much better). Just a fair warning, when you go to drill the hole in the hull to put the riva tip in, it will be the biggest PITA you might ever face.

    Is the TDR much louder than a gutted waterbox? In addition I'm sure it would provide better gains than oem box. I have some funding available for this month thanks to wife and looking to spend some.
