    '08 exhaust on an '04-'07 RXP

    Anyone tried this? Ditch the J-pipe for the straight midpipe and new '08 model waterbox by Riva? This is the same setup as the X skis. I was wondering what all needs to be done to run this on a 2004-2007 RXP and how big of gain if any was noticed.

    I'm currently in the process of doing this on my 2004 RXP. Just waiting on the parts to get here. I just ordered the exhaust parts, the special formed hoses for cool from the, and a riva X waterbox.

    What are all the needed parts? Is part 14 it other than the clamps? It includes 14-16. Let me know how the install works out for you.

    I just finished mine and it works great!! My wife can talk to me again while riding the ski. I noticed no loss of power, rpms. The only downside for me was you have to take the waterbox loose and slide it back to remove the supercharger. I used the 5 parts coming off the manifold then used the riva thru hull pipe to send it out the back. Good luck guys!!

    Alright, thanks for the info. If I run this I'm going to run it with the Riva waterbox.
