Exhaust Citroen C4 Cactus (2014-2020)

The exhaust system of the Citroën C4 Cactus (2014-2020 models, phases 1 and 2) includes flexible pipes, catalytic converters, exhaust pipes (universal or sport), and silencers. These parts are specifically designed for petrol engines such as the 1.2 VTi 82 HP (code EB2F/HMZ) and for BlueHDi diesel engines equipped with DPF and SCR systems to treat gases. The system functions to absorb vibrations, reduce noise, and manage thermal expansion caused by hot gases.

For diesel BlueHDi engines, the exhaust system integrates a Diesel Particulate Filter (DPF) and a Selective Catalytic Reduction (SCR) system, which help reduce harmful emissions. These diesel systems include dashboard warning lights indicating malfunction, potentially locking the engine if a fault occurs. Petrol engines typically use a catalytic converter designed for unleaded fuel combustion without DPF and SCR.

Key vehicle dimensions and specs influencing the exhaust system include:

• Length: 4.16 meters
• Width (excluding mirrors): 1.73 meters
• Height: 1.52 meters
• Wheelbase: 2.59 meters
• Front/Rear track width: 1.48 meters each
• Average weight: 1050 kg

These dimensions help determine appropriate pipe routing, flexibility, and placement of catalytic converters and sensors for optimal exhaust flow and emission control.

Compatible parts include:

• Exhaust pipes for petrol 1.2 VTi 82 HP models available as universal or sport versions, measuring 950-970 mm in length, weighing approximately 6-6.3 kg.
• Flexible exhaust pipes with various interior diameters (35, 45, 60 mm) and lengths (100-300 mm), designed to reduce vibrations and noise between engine, silencers, and catalytic converters.
• Universal rectangular catalytic converters (Euro 4 compliant), suitable for both petrol and diesel engines without sensor fittings, with entry diameter 48 mm and length 400 mm.

Always check compatibility using the exact engine code and model year to ensure correct fitment.

The exhaust system of Citroën C4 Cactus includes sensors that monitor catalytic converter and DPF performance. Faults detected by these sensors trigger warning lights on the dashboard and can lead to engine immobilization to prevent damage. Proper replacement and installation require ensuring sensors are correctly positioned and functional. If replaced, related sensors must also be replaced to maintain system integrity and compliance with emission standards.

To find parts, datasheets, and guides for the exhaust system of the Citroën C4 Cactus, focus on websites specializing in automotive components and technical data filtering by model, engine code, and year. Recommended sources emphasize genuine OEM specifications and include catalogues for pipes, catalytic converters, and flexible exhausts. Use specific search terms like:

• "Citroën C4 Cactus exhaust [year] [engine]"
• "Exhaust pipe flexible C4 Cactus 1.2 VTi"
• "Catalytic converter Citroën C4 Cactus Euro 4/6"

Ensure parts comply with relevant Euro emission standards and check for certification like E24-103R when available.

Choose exhaust components that are brand-new, manufactured to original equipment standards, and comply with European regulations. Quality parts will use stainless steel (such as INOX 409), high-performance ceramic monoliths, and advanced coatings to optimize durability and pollution reduction. Certified products by recognized bodies (e.g., TÜV SÜD) assure performance equal to or exceeding original parts. Also consider warranty coverage—typically 3 years or up to 100,000 km—and free returns policies to protect your purchase.

Here are some frequent questions:

• What could be causing unusual noises or rattles from the exhaust heatshield ?
• How can I check if my catalytic converter is failing or clogged ?
• What are the compatibility details of an exhaust deflector for my C4 Cactus ?
• Which materials are commonly used for exhaust system components and sensors ?
• Do I need a full exhaust kit or can I replace components individually ?

For all these, ensure professional diagnosis and verify OEM references for replacement parts. Proper installation, regular engine maintenance, use of recommended fuels, and timely sensor replacement help prolong exhaust system life and maintain emission standards compliance.
