It’s always been a wonder how Ferraris could get past modern noise emission tests, seeing how they scream their V8 or V12 hearts out.

However, some owners want them even louder. Take this guy, for instance, whose 458 Italia is far from being stock, as it’s boasting a Prior Design body kit, and an aftermarket set of wheels.

Looks aside, it’s the decibels produced by the straight-pipe exhaust that really caught people’s attention in a place crowded with exotics such as Monaco.

With the grunt matching its looks, this 458 might put out some extra horses from its 4.5-liter naturally aspirated V8 due to its special exhaust system. Even if it doesn’t, the stock car’s 570 PS (562 HP) and 540 Nm (398 lb-ft) of torque are more than good enough for a 0-100 km/h (0-62 mph) sprint in 3.4 seconds.
