Roll out the laws, 'cos this got stupid quick. I just googled it because I knew there was a purpose, and there was… it's called 'anti-lag' and it's a way of kicking the turbocharger into super-high RPMs through letting the exhaust explode with unburned gas. I remembered it from the launch of highly tuned rally cars, and it's a real thing, though it's a racetrack thing… I thought. And it's a turbo optimization thing. Nope! Apparently now they do it on NA aspirated cars where it's about as useful as trucks rolling coal. Even on turbo cars it's not NICE, but to tune NA cars this way is just ridiculous. Roll out the laws. This is deeply stupid.

The funnier part is, some turbodiesel and small displacement turbo gasoline engines already do in manifold burning to keep turbos spinning during gear changes, however they're tuned for city environments and it's neither noisy, nor popping. As you've said, the thing in the article is done just for the "cool factor", which is doubly bad. Also, motorcyclists' mental gymnastics about loud pipes are just unbelievable.

  As a new motorcyclist rider, loud pipes do not save lives, they just piss people off.

    More dangerously, they blind my ears. If I can't locate you, I can't provide you safe space, esp. if you're behind me, and possibly in one of my blind spots.

Knowing a hell of a lot about cars, both naturally aspirated and turbocharged, this comment just says a lot of gibberish. Anti-lag, or spooling, is an attempt to launch the vehicle with some boost built. Because in a turbocharged car you don’t build boost until enough exhaust gas goes through the exhaust turbine. An NA car will build no boost this way, as there is nothing to build boost. They are simply launching in their power band. The unburnt exhaust gas callout is also interesting. This is called running rich, and is a problem. Nobody specifically wants to run richer than they need to, and won’t have much unburnt fuel if if they’re tuned right.
