Exhaust Citroen C4 Grand Spacetourer (2018-2022)

The exhaust system for Citroën C4 Grand Spacetourer models (3A_, 3E_) fits multiple engine types including petrol versions 1.2, 1.5, 1.6, and 2.0. For diesel engines, there are specific exhausts designed especially for the 1.6 BlueHDi model, ensuring perfect compatibility and optimal performance.

The exhaust system mainly consists of flexible exhaust pipes and rear silencers (mufflers). Flexible pipes are installed between the engine, catalytic converter, and muffler to reduce noise and vibrations while absorbing thermal expansion caused by hot exhaust gases.

Rear silencers vary in length from 640mm up to 2100mm and weights range between 3.75kg and 8.08kg, depending on the specific model type.

Flexible exhaust pipes come in various diameters and lengths, priced including VAT as follows :

• 45mm diameter: 100mm (9.68€), 200mm (16.94€), 250mm (20.57€), 300mm (21.78€)
• 55mm diameter: 100mm (12.10€), 200mm (19.36€)
• 60mm diameter: 100mm (13.31€), 300mm (27.83€)

These flexible pipes play a key role in noise and vibration reduction within the exhaust assembly.

New rear silencers for the Grand Spacetourer range come at prices between 51.99€ and 290.5€, depending on the technical specifications and model type. These cover universal and sport variants optimized for noise reduction and exhaust flow.

Common symptoms indicating exhaust silencer issues include :

• Unusual or increased noise from the exhaust
• Loss of engine power or performance
• White smoke emerging from the exhaust pipe
• Visible oil or liquid leaks
• Noticeable holes, cracks, corrosion or rust on the silencer

If any of these symptoms occur, inspecting the exhaust system promptly is recommended to maintain car reliability and safety.

Minor damage such as small leaks or holes can be temporarily fixed using high-temperature repair bands or mastic. However, for significant issues like advanced corrosion, rust, or breakage, a complete replacement of the exhaust silencer is advisable for safety and durability.

• Minor damage: temporary repair possible with repair kits
• Major damage: full silencer replacement recommended

Proper maintenance ensures longevity and optimal car performance.

Yes, certain diesel engines, like the 1.6 BlueHDi model, use a specially designed EURO 6 catalytic converter suitable for vehicles equipped with SCR (Selective Catalytic Reduction) systems. This ensures optimal emission control in compliance with environmental regulations.

• 1.6 BlueHDi engine: dedicated EURO 6 catalytic converter available

Such specific converters contribute to reduced vehicle pollution and help meet stringent exhaust emission standards.
