If only everyone had high quality cameras and had pro recording skills lol

This is a short sound clip of a 2011 BMW 135i after a cold start. Car has N55 downpipe (n54tuning.com Performance Line) on stock exhaust, and custom Cobb/PTF stage 2 + tune. Listen how the sound starts out raspy and loud, but tones down and becomes throatier with a nice turbo whistle as soon as exhaust flap + secondary air pump closes. This sequence occurs at the 38 seconds mark...
Im thinking about getting Vibrant Performance resonators installed, to deepen the sound, and make it less raspy at cold start, and Wide Open Throttle.
