Nissan Cabstar Exhaust System Replacement Parts

The Nissan Cabstar in the UK ran across several distinct engine and emissions generations, and the exhaust system follows the engine code and emissions standard of the vehicle rather than its outward appearance. A system from an earlier Euro 4 era truck is unlikely to fit or pass MOT on a later Euro 5 or Euro 6 vehicle, even if the trucks look similar, because the pipe routing, mounting points, and aftertreatment components differ. Always match the exhaust to your exact engine code and emissions standard, and confirm compatibility with the breaker against your registration before purchasing.

Yes, this is one of the most important boundaries to be aware of: Euro 5 Cabstars and later Euro 6 models use different exhaust aftertreatment systems, with Euro 6 trucks typically requiring additional SCR (AdBlue) components integrated into the exhaust line that are not present on Euro 5 vehicles. This means a Euro 5 exhaust system is not a straightforward swap onto a Euro 6 truck and vice versa. Confirm with the breaker exactly which emissions standard your truck meets using your registration, and ensure the donor vehicle matches.

No — fuel type is a fundamental fitment factor for exhaust systems, and diesel and petrol variants use entirely different systems with different pipe configurations, manifolds, and aftertreatment components. The Cabstar sold in the UK was primarily offered as a diesel, so if you are sourcing a used exhaust, confirm the donor vehicle is also diesel and shares the same engine code as yours. Give the breaker your registration so they can verify the engine code match directly.

For fitment purposes, what matters is the engine code and emissions era, not the cab style or payload rating of the donor vehicle. Provided the engine code and emissions standard match, the exhaust system itself should be the same regardless of whether the donor truck was a single cab, crew cab, or different gross vehicle weight variant. That said, confirm this with the breaker against both registrations, as routing or mounting differences can occasionally exist between very different body configurations.

Almost certainly not without significant modification, and this is an area where you must be cautious: DPF-equipped exhausts have additional housings, sensors, and mounting provisions that are not present on pre-DPF systems, so the two are not directly interchangeable. Beyond fitment, fitting a DPF system from a different vehicle or removing a DPF entirely can cause an MOT failure. Specific DPF interchange questions are strong confirm-with-breaker territory — give the breaker both registrations and let them advise based on the exact part and engine codes involved.

For exhaust systems, trim level does not affect fitment — the exhaust follows the engine code and emissions standard, not the specification level of the truck. Whether the donor vehicle was a higher or lower specification makes no difference to whether the exhaust will fit, so you do not need to chase a like-for-like trim match. Focus your search on matching engine code and emissions era, and confirm with the breaker against your registration.
