    Aftermarket header question...

    I was just wondering if there is an aftermarket header for 05 RXP out there that would still utilize my stock j pipe and riva waterbox ?

    And also would an aftermarket header run fine with stock ECU and fuel ?

    what would be the point... the j-pipe is the bottelneck in the system
    that is why the X skis use a differant pipe

    so is there a different route i can take without doing a different header ? any type of j pipe mod etc ?

    yes the 08+ mid pipe type system flows a lot better
    just mod your riva box to take the "mid" pipe
