Second Hand Nissan NP300 Catalytic Converter

Yes, the NP300 Navara (produced from 2016 onwards in the UK) does have a catalytic converter as part of its exhaust aftertreatment system, fitted on all engine variants including the 2.3-litre dCi diesel. Diesel engines of this era typically combine a catalytic converter with a diesel particulate filter (DPF) and other emissions components in an integrated assembly. Because the exact configuration can vary by emissions standard and engine specification, always confirm the precise part required with the breaker against your registration number.

The NP300 Navara received a significant update around 2019-2021 depending on market, and while the 2.3-litre dCi engine carried across, emissions calibration and exhaust system specifications can differ between build dates. A catalytic converter that looks visually identical from an earlier car may not be a direct fit or could cause an MOT emissions failure if it does not match your vehicle's Euro standard. Name the generation boundary confidently but treat whether a specific cat crosses it as strong confirm-with-breaker territory — give your registration to the breaker and let them verify compatibility against the exact unit they have.

Trim level does not affect catalytic converter fitment on the NP300 Navara — the exhaust and emissions system is determined by the engine code and the emissions specification, not whether the vehicle is a Visia, Acenta, or Tekna. You may find cosmetic differences around heat shields or underbody trim panels between grades, but the cat itself is matched to the drivetrain. Focus on confirming the engine code and registration with the breaker rather than worrying about trim level.

The NP300 Navara 2.3 dCi was offered in both single-turbo and twin-turbo (biturbo) outputs, and while the base engine family is related, exhaust system components including the catalytic converter and its housing can differ between these variants because of differences in exhaust flow and emissions tuning. Do not assume a cat from a single-turbo car will fit a twin-turbo without checking — this is exactly the kind of interchange the breaker needs to verify against your registration and their donor vehicle's specification.

The NP300 (D23) and the previous D40 Navara are different generations with different engine configurations and exhaust designs, so catalytic converter parts are not considered interchangeable between them. Even where engine displacements appear similar, the emissions architecture changed significantly between generations. Always source a cat specifically listed for the NP300 (D23) and confirm the donor vehicle's registration and engine code with the breaker before buying.

Give the breaker your full registration number so they can confirm the engine code, build date, and emissions standard (Euro 5 or Euro 6) for your specific vehicle, as these directly determine which catalytic converter and associated DPF assembly is correct. Catalytic converter and DPF interchange is complex and the exact configuration can vary even within the same model year, so the more detail you can provide — including whether your van is single or twin-turbo — the better. Never rely on a visual match alone, as an incorrect unit may not fit properly or could cause an MOT failure.
