    Homemade RXP Free Flow Exhaust tubes

    I took the stock RXP-X exhaust hose piece I had left over and some 3" stainless steel pipe and made this exhaust hose,
    Hopefully whithout the exhaust hose touching the intercooler pipes, it will have a little more speed and less heat soak,

    PLEASE do not run that, UNLESS you have beads rolled in the ends(or welded) in that pipe !! The clamps will not hold the backpressure, and blow off! You will sink !.

    Ask me how I know......

    I have been running this the entire race season with out any failure, I am just now able to get a picture of it, I had to stretch the tubing to fit over the 3" pipe,
    heck it holds without a hose clamp on

    Sounds like you have been lucky so far.
    Maybe because its such a tight stretch, and your clamps are still holding.......
    At least weld a bead on each end, so the clamps wont slip past them. No bilge pump setup will stop a leak(or even slow it down) from a 3" hole .

    Better safe than sorry..

    Remember when those RXP's came for the first time to Puerto Rico back in 2004. By that time I was working in the only dealership of the island that was doing the warranty repairs . they were a blast and every spead freak wanted one. The first one we started to wreck lol.... we remove the big black resonator and replaced it with a plumbing tube (plastic one) we were a group of youngsters learning and used to work on 2 strokes lol..
    Found out that upgrade fail when almost sink the Craft .All of the sudden smoke started coming from under the seat . when removed ..SURPRISE..!!! Half of the bay flodded and the plastic tube on the exhaust melted lmao....!!! now i laugh at it but it was sure a big risk. So listen to the experts here .. Cheers..

    plus I am using the stock exhaust hose and after a while the heat makes it stick to the stainless pipe, I had to cut it, just to get it off, it seemed like it was glued after 2 endurance/sprint races,

    I have made one or two of these hoses. I used SS couplers and T-Bolt clamps. No failures.

    I have fitted a few home made free flows and never had a problem, I have always used T-Blots and fitted two on each end to be safe.
