hey mate was it a full system, eg headers to tip or just a cat back? Did you install it or did someone else install it?

head flange gaskets or the join under the car to the Y-pipe from the extractors.they come out with no head flange gaskets but its best to install them when you put extractors on

bullshit i got mine from autobarn about a week before xmas

oh and if it sounds like escaping air it's not a header flange, they make ya car sound like a diesel with a fcked lifter
it'll be extractor to cat or extractor y-pipe flange
