In interaction with the sports exhaust system, the variable intake manifold in synthetic material and featuring two switchable resonance flaps helps to ensure efficient gas cycles.
This results in an impressive torque curve, a high maximum torque and high power output across a broad engine speed range.
The sports exhaust system of the new 911 GT3 has two front silencers, two catalytic converters and one rear silencer, which discharges into the central twin-tract tailpipes. The large volume of the exhaust system reduces exhaust back pressure and thus increases power output.
In response to data provided by two Lambda sensors, the stereo Lambda control circuits regulate the composition of the exhaust gas separately in each exhaust tract. Another pair of sensors monitor pollutant conversion in the respective catalytic converters.
