    RXP Straight Pipe

    Unfortunatly my J Piep flex joint died and was leaking fuemes into my hull and effecting power so it had to go, I have been wanting to make a straight pipe for some time, I love it loud and cosidering this ski is only for the track noise isnt really an issue to me.

    At first I was going to just make a new mid pipe to go from mani to WB but I thought it was alot of work to not get what I really wanted.

    So I set about it. Its 2.5" internall diameter with3" over the top for that water jacket then into a mini WB to make sure the fumes are well mixed with water before going down 3" flexible marine exhaust onto a 3" outlet in the normal thru hull position.

    Currently I have the exhaust made and the WB made and Im just in the process of cutting up the metal for the jacket, thats the hard bit.

    I know that there prob isnt much power gain to be had but im certain that there will be low down throttle response improvement which is what I want for getting round a course.

    My setup also does away with the bell on the maini and is jacketed right upto the mani.

    Should be good, no muffler 8800 rpm!! Im hoping for some banging when she comes unhooked.

    Les likes to cut spark and not fuel on the limiter so there will be some unburnt bang bang juice going down there lol.
