This advice is designed to provide basic guidance to traders. It is not a complete or authoritative statement of the law. A large print version is available.
Regulations to set permissible noise levels for most replacement motorcycle exhaust systems were introduced in August 1996 by The Motorcycle Silencer Regulations 1995.
This means that replacement silencers and exhaust systems have to be manufactured to meet specific British, European, or International noise reduction Standards.
Under the controls, exhaust systems have to be indelibly marked with the approval mark or the appropriate Standard of compliance.
Examples are shown below:
or BS AU 193/T2
In addition, the packaging in which exhausts are sold must be marked with:
the manufacturer’s name or trade mark and address.
Instructions, where necessary, for regular maintenance.
The regulations DO NOT APPLY to the following six categories of exhausts:
silencers and exhaust systems for off-road bikes and which are indelibly marked “NOT FOR ROAD USE”.
silencers and exhaust systems for older machines and which are indelibly marked “PRE 1985 MC ONLY”.
exhausts sold fitted to a motorcycle.
silencers and exhaust systems sold for export.
exhausts sold as scrap.
Supplying exhausts which do not meet those requirements may amount to a criminal offence. The penalty can be fine of up to £5,000 and/or a 3 months jail sentence.
