Abstract

An engine emission restrictor (1) comprises a sleeve (3) and a stopper portion (4), the sleeve (3) being attached or attachable at or towards the end of an exhaust pipe (2) of or for the engine, the stopper portion (4) being releasably attachable to or within the sleeve (3) and serving, when fitted to, impede or prevent the flow of exhaust fumes out of the exhaust pipe (2). The engine emission restrictor may be particularly useful for securing a vehicle against theft, since when fitted to the exhaust pipe (2) of a vehicle the vehicle may not be easily driven away, if at all. A method of securing a vehicle utilising the engine emission restrictor (1) is also described.
