You already expect good power from its 2-liter turbo engine, but if the back of the TTS boasts an Akrapovič Slip-On exhaust system, it offers even greater power. Precision-made of our proprietary titanium, this exhaust system offers significant weight reduction and a sportier sound. The Akrapovič performance exhaust weighs less than half than the stock system. With the increase in power it improves the power-to-mass ratio of this four-wheel-drive sports car even more noticeably. Power delivery is improved especially in the low and mid rev range and with further gains at the top end. The effect on sound is significant, adding a deep, resonant, sporty sound without any droning. Complete the look with a set of four exquisite 100 mm titanium tailpipes.
