It's the same as a JCB3C or D and David Brown, the silencer fits over a short manifold stubby tube. It just slide off ( or should).
I had 2 chrome side pipes, mounted up from behind the front wheels and bolted to the lorry mirriors on the side of the windscreen, when I fitted my V8.
As long as it doesn't emit a louder noise than a standard 2.25 Diesel and does't leak, it's OK.
Method of Inspection
1. Examine the condition of the whole exhaust system, including the silencers and mountings, for security, deterioration and completeness
2. With the engine running
a. check the exhaust system for leaks
Note: A durable repair to an exhaust system which effectively prevents leaks is acceptable providing the system is structurally sound
b. assess subjectively the effectiveness of the silencer in reducing exhaust noise to a level considered to be average for the vehicle.
Reason For Rejection
1.
a. A part of the system missing or excessively deteriorated
b. an exhaust system mounting missing, or In such condition that it does not fully support the exhaust system.
Note: An alternative mounting device is acceptable providing the system is secure and the fixing is not likely to fail prematurely-
2.
a. A major leak of exhaust gases from any part of the system
Note: A minor exhaust leak from, for example, a connection joint or a pin hole, is not a Reason for Rejection
b. a silencer in such condition, or of such a type, that the noise emitted from the vehicle is clearly unreasonably above the level expected from a similar vehicle with a silencer in average condition.
