Fitment questions
What years of Mazda 6 exhaust will fit my car?
The Mazda 6 ran across three generations in the UK: the GG/GY (2002–2007), the GH (2008–2012), and the GJ (2012–2018, with a facelift around 2015). Exhaust systems are generation-specific and tied closely to the engine code and emissions standard of your car, so parts from one generation will not generally fit another. Always match by engine code and fuel type, and confirm compatibility with the breaker against your registration plate.
Will a pre-facelift Mazda 6 GJ exhaust fit a post-facelift GJ (2015 onwards)?
The GJ facelift arrived around 2015 and brought emissions and engine updates that can affect exhaust specification, so a system from a pre-2015 GJ may not cross that boundary cleanly even though the bodystyle looks identical. Name the boundary to the breaker and ask them to check engine codes on both donor and recipient vehicles before purchasing. Never assume a visual match means a correct fit across a facelift year.
Does the exhaust differ between a Mazda 6 SE, SE-L, Sport Nav, and GT Sport?
Trim level — whether SE, SE-L, Sport Nav, or GT Sport — does not determine which exhaust system is fitted; what matters is the engine code, fuel type (petrol or diesel), and the emissions era of the vehicle. Parts sourced from a higher or lower trim will fit the same way provided the engine and emissions specification match, though minor cosmetic differences such as tailpipe finisher style may vary and should be expected. Confirm the engine code with the breaker rather than shopping by trim name.
Does a Mazda 6 diesel exhaust have a DPF, and can I swap in one without it?
Mazda 6 diesel models sold in the UK do carry a diesel particulate filter as part of the exhaust system, and fitting a system without a functioning DPF will cause an MOT failure under current UK regulations. Whether a specific used DPF or cat-back section from a donor car is compatible with your exact engine code and emissions calibration is something you must confirm directly with the breaker against your registration. Do not assume any diesel exhaust section is a straight swap without verifying DPF integrity and specification.
Is the exhaust the same on the Mazda 6 saloon and estate (tourer)?
The saloon and estate (Tourer) bodystyles were both offered across the GH and GJ generations, and the rear exhaust sections can differ in routing and length between the two body styles even where the engine is identical. Always tell the breaker which body style your car is as well as the engine code, so they can pull the correct donor part. Confirming by registration is the safest approach given how similar the two can appear in parts listings.
Will a Mazda 6 GH exhaust fit the earlier GG generation?
The GH (2008–2012) and GG (2002–2007) are separate generations with different platform dimensions, engine families, and emissions standards, so the exhaust systems are not interchangeable between them. Attempting to fit a GH system to a GG car would require modifications and could produce an MOT failure if emissions components do not match your vehicle's type-approval. Stick to parts sourced from the same generation and the same engine code as your car.
