McLaren 650 & 650S Valvetronic Cat Back Sports Exhaust

The item listed is a sports, aftermarket, valved Catback system to fit McLaren 650 series, 2014 onwards. This precision-engineered stainless steel valved exhaust system reduces the weight of your McLaren and improves torque and horsepower, both as a result of weight reduction as well as a free-flowing system by comparison to OE. Our Valvetronic system includes opening and closing valves which is controlled by the vehicle ECU, therefore working the same way that the original exhaust was designed to function. We've extracted additional power through improved gas-flow dynamics and a drop in backpressure. To complement our muffler design, we've added our well-known exhaust valve system to create a virtual symphony from the large displacement V8. 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 noise from this system is similar to the OE (original exhaust) but is a more aggressive sports sound with the valves open. 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.
