2 Boxster S t win tailpipemonitors each cylinder bank separately.
For each exhaust tract, four correspond -
ing oxygen sensors regulate the composi -
tion of the exhaust gas and monitor the
performance of the catalytic converters.
Having separate tracts means that the
exhaust gas can flow more freely. The
resulting reduction in pressure loss has a
positive impact on power output, torque
and the unmistakable engine sound.
Available as an option for the Boxster
models is the sports exhaust system
including sports tailpipe. It produces an
even more resonant Porsche sound.
Our cross-flow cooling system, as used

in motorsport, supplies each engine
cylinder uniformly with coolant, which
protects the valves against thermal
overload and, therefore, premature wear.
This improves combustion and keeps
emissions, fuel consumption and noise
comparatively low.
Exhaust system.
In the Boxster models, each cylinder
bank has its own stainless-steel exhaust
tract. Downstream of their respective
rear silencer, the tracts converge into a
connecting tube and a single ( Boxster)

Thermal management.
The Boxster models feature a new version
of thermal management to reduce friction
losses that arise during the warm-up
phase.
Thanks to the selective control strategy
and on-demand, gradual activation of the
various cooling circuits, the engine and
gearbox warm up to normal operating
temperature more rapidly. The conse -
quent reduction in friction also reduces
fuel consumption and CO

During sporty driving, thermal manage -
ment also acts to reduce temperatures
so that a high level of performance is
maintained.

Please note that circuit racing, trackday
use and other forms of performance

driving can significantly reduce the
service life of even the most durable
pads and discs. As with conventional
high-performance braking systems,
represents a major reduction in unsprung and rotating masses. The consequence of
this is bet ter road holding and increased
comfort, particularly on uneven roads,
as
well as greater agilit y and improved
handling.
Another key advantage of PCCB is the
extremely low weight of the ceramic
brake discs, which are approximately
50
% lighter than standard discs of similar
design and size. As well as enhancing
performance and fuel economy, this
