Exhaust Types

The smart fortwo 451 has 2 different types of exhaust for the petrol engine. The removal of both of these types are covered in this guide.

Euro 4

The Euro 4 exhaust was a far more simple design. Both the turbo and non turbo exhaust were exactly the same. The main body of the exhaust contained a CAT and the silencer. It made it easy to change but was more expensive.

Euro 5

The Euro 5 exhaust had a longer route for the gas to travel. Both the turbo and non turbo exhaust were exactly the same. The main body of the exhaust only contained the silencer. The CAT was a separate part further upstream.

Smart used a separate CAT as it was cheaper and easier to produce. The upside of this design is that you can change the silencer on its own for a silencer with Brabus tips. You aren’t buying the CAT so it’s cheaper.

Removing The Euro 4 Exhaust

Remove the rear panels and take off the rear crash bar to access the exhaust.
