The precision-engineered titanium alloy Slip-On performance exhaust system reduces the weight of this supercar and improves handling. We’ve extracted additional power through improved gas-flow dynamics and a drop in back pressure. To complement our muffler design, we’ve added our well-known cast titanium dual-mode exhaust valves to create a virtual symphony from the large displacement V10. If no optional Akrapovic sound kit for adjustable sound is used, at lower engine speeds and during cruise operation the valves are closed and produce a deeper and sharper exhaust note. At wide-open throttle the valves open, releasing the full fury of the engine. The driver can control the sound with the Akrapovic sound kit. Complete the look with a set of four exquisite tailpipes in carbon fibre.When installing Akrapovič aftermarket exhaust system that was developed for use on closed tracks, we recommend remapping the ECU in order to prevent potential »check engine light« warning signals.
