^^^^^ what he said.. i had a medium sounding tishhh from the divert since i fitted a big **** cone filter, but as said, its chatters/flutters quite loudly now. was not expecting any change just because i fitted a boost gauge! Bonus i say i love the chattery sound.
will post pics up of me gauge later when it gets dark. i also fitted R8 like lights as well i would like some comments on the chavyness! lol
