That's what a broken exhaust sounds like, especially on a Porsche flat six. A properly designed one should not crackle or bang. Those are modern affectations of the Audi driving crowd with their bypass valves.
An exhaust note should be smooth and refined, with a muted, perhaps slightly menacing note in the low numbers, hinting at the unbridled amounts of power yet to come. And it should rise gently to a shrieking crescendo when the revs rise.
