    RXP-X through hull exhaust options

    Just got my first four stroke ski a 2008 RXP-X and have been searching around here for tha past few days. I was mainly a pwctoday user since I only had two strokes. My question is what are the through hull exhaust options. Do I have to relocate the intercooler to use the riva kit?? I really like the sound of the through hull but I dont know if I like it enough to spend 500 bucks to move cooler.

    Thanks in advance!!

    OEM outlet
    single through-hull

    Unless you start to modify yourt craft, leave it OEM. After you get the speed bug, you will end up spending the money to move the IC and go Riva through-hull...cleans up the hull to make wrenching a bit easier. So I' understand.

    There is no need to relocate the intercooler. Just get the outlet kit, waterbox and the exhaust coupler.

    Stock X box with thru Hull plumbing sounds good and performs well.
    I ran a x box gutted thru hull on T-X. Was a sweet setup and is still on the ski. I also ran a Gibson and TDR in T-X.
    The stock X box is not as loud, but sounds good.

    is this possible to do on a 09 rxpx? looks like it should work with a 90* bend off the stock water box.

    The riva rear exhaust kit is what you need. good sound and you get a discount if you buy it off this site with the greenhulk code.
