want to install beta engine cover

I'm thinkin of installing the engine cover on my beta accent but before i do, doe's the plastic cover that shroud's the beta head really hush the car up?

i mean, i've droven xd's and they're hush as a bentley..

i alway's wondered why i hear the engine so loud in my beta accent, like a metal whiring sound when revved to redline and the sound of the valvetrain knacking knacking..exposed head maybe?


so..who has a engine cover they can either give or sell to me?
