♦
After working on the exhaust system, ensure that the system
has sufficient clearance to the bodywork. If necessary, loosen
double clamp on front exhaust pipe and realign silencer and
exhaust pipes.
♦
Do not use sealants containing silicone. Silicone particles
drawn into the engine will not be burnt in the engine and will
damage the Lambda probes.
