The new Evolution system makes the Panamera noticeably louder, with a deep and very aggressive sound that fully expresses the racing-oriented nature of this exhaust, which is made of our proprietary titanium alloy. This beautifully crafted titanium exhaust system consists of four round tailpipes, computer-optimized asymmetrical mufflers with a dual-mode exhaust valve system, and a link pipe with a resonator to eliminate any chance of incabin droning. The dual-mode system can be used with the Panamera GTS factory button to regulate the exhaust valves. This Evolution performance exhaust not only transforms the Panamera’s nature with a racing look and especially sound, but also adds more power and reduces weight.
