    GreenHulk's choice - RXP-X 260 Performance Kit

    I often get asked via PM or email what I would do to a RXP-X 260 if I were to build one up to be both fast and reliable. These parts are exactly what I would choose.

    Putting this list together makes me want to go buy one and build it up....

    So no exhaust ? Stock one yields good performance? I don't like noise either.... What top end would you expect with a 8800 rev limit?

    ahhh, thanks for the reminder. I like mine LOUD!!! I edited my build list above to include the following
    Riva Waterbox

    Riva Rear Exhaust Kit

    With 8800 limiter and a good hull I think 82 mph is dooable

    Of course I would eventually, but you know I always start off slow and then pop the turbo on when I get bored with it

    So stock exhaust is OK for performance, and quiet enough?

    For folks who prefer low noise, what are the good performance choices?

    How fast can stealth go?

    Stealth can go faster than you might think

    You can even run a turbo through the stock exhaust

    Anyone care to comment on what they would do or where they would stop if they were to do it again? I've got a very heavily modified Subaru, if I were to do it again I would do it much simpler and leave it much closer to stock. That's the advice that I would like. Someone who has done it once and knows where it turns from fun to obsession.

    I've got a stock RXPX 260, is there anything I can do if I want no added maintenance and "stock like" reliability? Comments appreciated. I've searched the forums and read the posts, most of which mentioned the "modifying icontrol ski's" thread but coming from someone looking for this information, that thread doesn't help except to describe the type of modifications people do.
