I agree, if you're concerned with loudness, look at those with extra baffles and packing. My dual in dual out Magnaflow (#14385) sounds like it has similar behavior to Orion's 4" round. Low, deep, but very loud and ricey at mid acceleration (but in hard acceleration - I love the sound!).

BTW Orion, what made you decide on that particular model? ease of fit? sound?
Nice job!
