SO - Slip-OnThe 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.THIS PRODUCT DOES NOT MEET EMISSION COMPLIANCE REQUIREMENTS FOR STREET OR HIGHWAY USE.PERFORMANCE: Unit Stock Akrapovic Max gain Maximum power kW 385.0 / 7710 rpm 391.0 / 7680 rpm + 11.0 / 3820 rpm HP (m) 523.5 / 7710 rpm 531.6 / 7680 rpm + 15.0 / 3820 rpm HP (i) 516.3 / 7710 rpm 524.3 / 7680 rpm + 14.8 / 3820 rpm Maximum torque Nm 518.0 / 6490 rpm 528.0 / 6260 rpm + 27.0 / 5000 rpm lb-ft 382.1 / 6490 rpm 389.4 / 6260 rpm + 19.9 / 5000 rpm Weight kg 32.0 14.0 - 18.0 lb 70.6 30.9 - 39.7 % - 56.3 Noise dB 87 / 3750 rpm 89 / 3750 rpm 2 Installation time min 240
