    Dual exhaust for Ultra 300 /310

    I came across this build recently from Europe and though dual exhausts have been used on race skis especially standups since the early 90s just don't see why skis aren't modifying for this as much today to unleash an additional 10-15 HP..

    Im talking about a "true" dual exhaust running one down pipe from the exhaust manifold then a Y pipe going to each WB then each pipe from the box out the tail exhaust ,not just one pipe from exhaust manifold down pipe running from one WB to the other WB ..

    This ski Was built in Finland and has raced WFs and the big Acropolis Raid offshore in Greece and I'm sue other International events..

    Would luv to get a few pics of inside the hull setup ,maybe others would be curious..

    I seen a few but lost them on my PC somewhere..

    "Could be" some gains, but probably not enough for the increased hassle of reaching / servicing other areas on the Ski (like Exhaust Filter / Oil Filter). Would this require 2 Exhaust Filters?

    I don't know about the rest of you, but it is already challenging to get to that Oil Filter!

    Interesting but could be some unforeseen headaches with this. JB

    i cant see any gains on a stock engine, the engine can only produce so much exhaust gas of which is already being dealt with

    Probably not people here just dont or arent allowed to share much. More so the fact im sure they dont need to be told how what theyre doing isnt going to work hahaha. Sambos thread is a good example, he wanted a turbo and he got one
    theres a few people i know with real headers, turbos, strokers, big pumps, etc
