    nope,

    just keeps it running the way it should with no exhaust gases getting into
    inlet system when the reed valves fail.
    other than that, no performance gain.

    but they do look fast

    ATF Test/Reading

    As sirbreaksalot said there is no ''real" performance gain...

    The only thing I can think of that some may call a performance gain is the ability to get a much much more accurate reading on Air-to-Fuel (ATF) ratio due to the fact that with out the block off's there is fresh air that is being drawn through the air-intake that is being put through the exhaust and if you try to get an ATF reading with out the block off's it will not be a accurate reading due to the fresh air in the exhaust giving an untrue ATF reading
