Hey how does it rate 1=stock and 10=straight pipe. I have the cat cut out also and want a 4040xl but it cant be too loud.

Well since I have never straight piped it, it's hard to answer that. But I would say about an 8. There is no drone in the cab and once your up to highway speeds, it almost is quiet as stock. But put a load on it and driving around town at low RPM's is loud but not too loud.
