exaust leak

How "small" is the leak? I purposely loosend my system just to pass emissions when i first bought my car and it barely passed. Exactly where is the leak coming from or do you not know? Though i've heard if it's too much of a exhaust leak the sniffer can tell, of course I dunno if that's true or not I was just told that. Only way to find out is go and try passing and see what happens.
