Everytime you start cold powerfull engine (naturally aspirated especially), you get a noise you will not forget. Why?

In the range of first 30 – 90 seconds, ECU is in a mode which heats up the catalysts by providing unnaturally petrol rich mixture that burns very late in the proces of a 4-stroke internal combustion engine. The outcome is something every petrol head loves to hear, and neighbourghs probably too 🙂
