The burble and pops are from fuel combusting on the way out of the engine so not really something that is designed in, it's caused by over fueling so I would love to see the blurb where it says that it was part of the SVO teams remit to make the SVR sound that way.

Yes, exactly. In most applications once you lift off the throttle, fuel delivery is cut, the injectors cease to work momentarily. In order to achieve the pop/bang effect, there is a different strategy, namely a small amount of fuel is still being injected, however it happens right when the exhaust valves are open, so the fuel burns downstream the exhaust system with pops and bangs. This is fairly easy to implement in direct injection engines and these tactics are widely used by performance divisions of most modern manufacturers.

Here's the detailed explanation, please take note of slide 6 where this exact fueling strategy is described in regards of the SVR:
