Second Hand Nissan Pulsar Catalytic Converter

Yes, all petrol-engined Nissan Pulsars (sold in the UK from 2014 to 2018) have a catalytic converter as part of the exhaust system. The 1.2-litre DIG-T turbocharged petrol and 1.6-litre DIG-T turbocharged petrol variants both carry a cat, as does the 1.2-litre naturally aspirated petrol. There was no diesel Pulsar sold in the UK, so every UK-market Pulsar has a catalytic converter rather than a DPF setup.

The Nissan Pulsar ran from 2014 to 2018 as a single generation, but there was a facelift around 2016 that brought updates which may affect exhaust components. The catalytic converter follows the engine code and emissions calibration of the car it was built for, so a pre-facelift unit and a post-facelift unit should not be assumed to interchange even if they look similar. Confirm the exact engine code and model year of both the donor and your car with the breaker before buying.

Yes, the engine code is the most important detail to match — the 1.2 DIG-T (engine code HRA2DDT) and the 1.6 DIG-T (MR16DDT) have different exhaust systems and their catalytic converters are not interchangeable. Always quote your engine code, which you can find on your V5C or by asking a breaker to check against your registration. Never assume that matching the engine size in litres alone is sufficient.

No, trim level does not affect catalytic converter fitment on the Pulsar — the cat is determined by the engine code and the emissions standard the car was built to, not by whether it is a Visia, Acenta, or Tekna. You may find minor differences in surrounding heat shielding or bracketry between cars, but the core catalytic converter unit follows the engine, not the trim. Focus on matching engine code and year rather than trim name.

2016 sits right at the Pulsar facelift boundary, meaning some early 2016 cars are pre-facelift and some later 2016 cars are post-facelift builds. This matters because the emissions calibration and potentially the exhaust configuration may differ across that boundary, and fitting a cat from the wrong side of it could affect emissions performance or MOT compliance. Ask the breaker to verify the exact build specification against both your registration and the donor vehicle's registration before proceeding.

Yes, fitting a catalytic converter from the wrong engine variant or emissions era can result in an MOT emissions failure, even if the part physically bolts on. The catalyst formulation and light-off characteristics are matched to a specific engine and ECU calibration, so a visually identical unit from a different engine code or model year may not clean exhaust gases adequately. Always confirm the donor part matches your exact engine code and year with the breaker, and if in doubt ask them to cross-reference against your registration plate.
