The exhaust system of the vehicle shall comply with the following requirements:Exhaust manifold(a)The exhaust manifold and the section of the exhaust pipe adjacent to the manifold shall be shrouded with a metal cover to prevent petrol, oil or other combustible material from coming into contact with the hot metal. If the manifold cannot be effectively protected in such a manner a drip tray shall be provided under the carburettor with drain pipe to direct waste petrol away from the manifold and exhaust pipe.Tail pipe spark arrestor(b)The tail pipe of the exhaust system shall be fitted with an approved type of spark arrestor. Because of the rapid ease with which screen type arrestors can collect carbon, they must be serviced regularly to ensure that they remain in an efficient condition.
The entire exhaust system from the exhaust manifold to the tail pipe should be checked regularly to ensure that there are no gas leaks.Fuel system
