Exhaust Nissan NV400 (2010-2024)

The Nissan NV400 exhaust system includes key elements such as the exhaust manifold (for dCi 145-146 HP diesel engines, diameter 302 mm), rear muffler/tailpipe (specific for 2300 cm³ engine models), and exhaust pipes fixed by flanges with 56 mm inner diameter and 60 mm outer diameter, secured with clamps.

The NV400 is available with diesel dCi engines, notably:

• dCi 150: 150 hp with a maximum speed of 155 km/h
• dCi 145-146: earlier variant with similar power

Yes, replacement exhaust parts such as catalytic converters and pipes for the NV400 are available. These parts meet technical specifications and fit corresponding engine variants. For comprehensive maintenance and replacement guidance, it is recommended to consult authorized dealers and specialists.

Different exhaust smoke colors can indicate specific issues :

• White smoke may indicate coolant leaks or fuel combustion problems.
• Blue smoke often signals oil burning inside the engine.
• Black smoke can result from excess fuel or incomplete combustion.
• Two-colored smoke generally points to mixed issues and requires inspection.

Proper diagnosis by a professional is advised to maintain fuel efficiency and reduce emissions.

Quality exhaust parts, such as catalytic converters and DPFs, should comply with manufacturer specifications and European regulations. Use of high-grade stainless steel (like INOX 409) and high-performance monoliths treated with advanced coatings ensures durability and efficiency. Warranty coverage and proper certification (e.g., TÜV SÜD) also reflect quality assurance.

Exhaust parts, including diesel particulate filters (DPF) and catalytic converters, come with a 3-year warranty limited to 100,000 km of use. Unused parts in original packaging may be returned within 30 days. Warranty coverage requires professional installation following all manufacturer assembly and maintenance instructions.

• Warranty covers only parts installed by authorized professionals.
• Negligence or improper use voids the warranty, especially clogged DPFs.
• Return shipping responsibilities vary outside the EU.

Always follow proper maintenance to ensure longevity and compliance.

The catalytic converter is a critical exhaust component designed to reduce emissions by converting harmful gases into less harmful substances. It is typically integrated downstream of the engine and upstream of the muffler. For the Nissan NV400, it must be compatible with engine displacement and fuel type, running strictly on unleaded petrol if applicable.

• The Lambda sensor is usually replaced during catalytic converter replacement (around 80,000 to 100,000 km).
• Connections used near catalytic converters should be copper to ensure tightness and proper function.

Using a certified catalytic converter helps maintain compliance with emission standards.
