­Sports exhaust system.
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
