    Default K&N conical air filter really hissy

    Hi
    I just fitted a K&N air filter to my corsa vxr 11 plate.
    My friend got it through his work and it's quite a big filter.
    When I'm driving its fine runs fine drives ok but it hisses a lot instead of growls.
    You can hear the dump valve a lot more which is good and the turbo whistle is much louder but there is no growl.
    Any ideas on how to make it more growly?



    Thanks

    A cone won't 'growl' as much on a turbo car buddy you will mainly get a sucking / hissing noise due to the sound of the turbo spooling being amplified. The growl you hear from cars is on a na engine.

    Is there any way to quieten the hissing a bit?
    Would a panel filter give more of a growl?

    In short no that's how they sound even with a panel filter you still get the same noise just a little quieter
