Capristo has released this dyno video of a Lamborghini Aventador fitted with its new exhaust upgrade.
Once fitted to the 6.5-litre V12 lump, the system with X-Pipe section sees output raised from 515 kW (700 hp) to 551 kW (739 hp). But the power increase almost pales into insignificance once you experience the symphony it provides.
Turn your speakers up.
