Max output for the B5254F is 170 hp
(125 kW) at 6000 rpm. Max torque is
220 Nm at 3300 rpm. Thanks to the
V-VIS system, 90 per cent of the
maximum torque is available between
2000 and 6000 rpm.
Exhaust system
Figure 18
The exhaust manifold is a welded ex-
tractor design. Five separate pipes,
each with appr 400 mm length, com-
bines performance with low weight
and short light-off time. The choice of
materials is a combination of ferritic
and austenitic stainless steel qualities.
The manifold is connected to the ex-
haust system by a flexible joint and
springloaded bolts. The system has
one main silencer and a combined
catalytic converter and silencer. The
location of the main silencer is in the
middle of the exhaust system to en-
sure good attenuation at low fre-
quences. The silencer inside the cat-
alytic converter is located behind the
catalytic area for the same reason.
The entire system has been fine-tuned
in order to retain an "appealing" en-
gine sound which enhances the ex-
perience of driving pleasure but sup-
press noise. The tail pipe ending is of
large diameter pipe and straight.
