Cheap Mercedes-Benz GLA Exhaust System

The GLA (X156) ran from 2013 to 2020, with a facelift in 2017, and that facelift year is a meaningful boundary for exhaust components because pipe routing, mounting points, and emissions calibration can differ between pre- and post-facelift cars. If both cars share the same engine code and the donor is from the same pre- or post-2017 phase as yours, there is a reasonable chance of a match, but crossing that 2017 boundary means you should confirm the specific part numbers with the breaker against your registration before buying.

No — the 200 is a petrol engine and the 220d is a diesel, and these use entirely different exhaust systems including different pipe configurations, a diesel particulate filter on the 220d, and different catalytic converter setups. Engine code is the key matching point here, and a petrol exhaust will not interchange with a diesel one regardless of the year or body. Always give the breaker your engine code alongside your registration.

Trim level — whether your car is an SE, Sport, AMG Line, or Urban — does not affect which exhaust system fits, as the system follows the engine code and emissions specification rather than the trim. The one exception worth noting is the AMG GLA 45, which uses a completely different high-performance engine and exhaust, so that is a separate part entirely. If you have a standard trim GLA with the same engine code as a donor car, trim differences are not a concern for fitment.

The GLA moved to Euro 6 emissions standards around 2015–2016 depending on engine, and Euro 6 systems are calibrated to work with updated engine management and tighter emissions hardware, so swapping a Euro 5 system onto a Euro 6 car risks an MOT failure on emissions even if the pipes bolt up physically. You should treat the Euro standard as a hard fitment boundary and match donor and recipient cars on both engine code and emissions era. Confirm the exact Euro status of any donor part with the breaker using your registration.

For the GLA, the front pipe or downpipe section is the most critical part to get right because it connects directly to the turbo or manifold and, on diesel models, integrates with the DPF and catalytic converter; mismatches here are both a fitment and an MOT risk. Rear sections such as the centre pipe or back box are generally less emissions-sensitive, though mounting positions still need to align with your specific engine and pre- or post-facelift build. Whether individual sections from different donor cars can be mixed is strong confirm-with-the-breaker territory — give them your registration and engine code for each section you need.

Both are diesel engines in the X156 GLA, but they have different engine codes — the 200d typically uses the OM626 and the 220d the OM651 in earlier cars — and the exhaust systems, including DPF configuration, are matched to those specific codes. On paper these are different parts, and fitting the wrong one could cause running issues or an emissions failure at MOT. Confirm the engine codes of both cars with the breaker before agreeing a sale, as DPF and catalytic converter interchange specifics are not something to assume.
