Vehicle Safety Branch Examiner’s Instruction
Vehicle Intake and Exhaust Systems
Pre ADR 27C Vehicles
There is evidence to suggest that many ‘hang-on’ emission control devices for these vehicles
are no longer available from original equipment manufacturers and/or spare parts suppliers.
This applies to vehicles manufactured prior to 31 January 1986.
Taking into consideration the non-availability of emission control components, examiners do
not need to insist on original equipment emission control systems being intact.
Consequently vehicle examiners do not need to issue a modification permit for exhaust
extractors.
It is also unnecessary to issue a modification permit for non-genuine air filters providing
induction noise is not excessive. These include cone or pod type filters.
Not withstanding the above, vehicles must continue to comply with the Road Traffic (Vehicle
Standards) Rules 2002 with respect to the emission of smoke.
Post ADR 37 Vehicles
Vehicles manufactured from 1 February 1986 must continue to comply with the applicable
design rule for the year of manufacture (Australian Design Rule 37/00, 37/01, 79/00 or
79/01).
Catalytic converters and other emission control devices must be retained and functioning
correctly. However where exhaust extractors are fitted a modification permit is not required.
It is also unnecessary to issue a modification permit for non-genuine air filters providing
induction noise is not excessive and that all engine management sensors are fitted and
operating. These include cone or pod type filters.
