You sure?:-
'EXHAUST SYSTEM
The decibel level will be assessed at the discretion of the tester, other checks are:
The exhaust mountings must be secure and not fouling any part of the rear suspension
The exhaust must not be holed and free from leaks from both joints and box(es)
Replacements units, other than bikes registered before 01.Jan.1985, must have the BSAU 193 stamp'
Over 90db don't get a BSAU stamp.......ergo...
Edit, from MAG Themselves:-
The law says that your bike will fail the MOT if:-
a. Any part of the exhaust system is missing or excessively deteriorated.
b. A leak in an exhaust system which causes excessive noise to be emitted.
c. An exhaust system mounting missing or one which is in such a condition that it does not fully support the exhaust system.
d. silencer which is in such a condition or is of such a type that the noise emitted is clearly in excess of that which would be produced by a similar machine fitted with a standard silencer in average condition.
e. A silencer fitted to a motorcycle first used on or after 1 January 1985 which is not marked with either:-
* The make and type specified by the motorcycle manufacturer.
* British Standard classification BSAU 193 or BSAU 193a or an EEC approval number prefixed by a small 'e' marking or an ECE approval number prefixed by a capital E.
* A silencer marked 'NOT FOR ROAD USE', TRACK USE ONLY' or similar words.
The recent change in regulations in essence say that the only issue regarding the type of exhaust is that it should not contain any notice on it which indicates that it is not for road use. As far as the noise is concerned the regulations are quite wordy but boil down to the Tester being able to fail the exhaust if the noise emitted is “clearly in excess”, of what would normally be expected. You might get an "adviser", the Tester might fail it!
