Second Hand BMW X7 Exhaust Manifold

Yes, all BMW X7 variants have exhaust manifolds — these are the cast metal components that collect exhaust gases from each cylinder bank and feed them into the downpipe and catalytic converter system. The X7 uses turbocharged petrol and diesel engines across its range, and all of these have exhaust manifolds as standard (on the V8 and inline-six engines you will have one manifold per cylinder bank). There is no naturally aspirated engine option on the X7 where manifold design would differ fundamentally, so this is a genuine fitment requirement for all variants.

The BMW X7 (G07) launched in 2019 and received a significant facelift in 2023, which brought updated engines and revised underbonnet layouts alongside the exterior and interior changes. Because the facelift introduced updated engine variants, an exhaust manifold from a pre-facelift 2019–2022 car may not be a straight swap onto a 2023-onwards model even if the engine code appears similar — always confirm the exact engine code on both vehicles with the breaker before ordering. Fitment is driven by engine code, not model year alone.

Engine code is the single most important factor — the X7 has been available with multiple engines including the B57 3.0-litre diesel, the B58 3.0-litre petrol, and the N63 4.4-litre twin-turbo V8 petrol, each of which has a completely different exhaust manifold that will not interchange with the others. You must match the donor car's engine code exactly to your own, which you can find on your V5C or by asking a breaker to check against your registration. Never assume manifolds are interchangeable just because both cars are X7s.

Trim level itself (for example whether the car is standard, xLine, M Sport, or M50i spec) has no effect on exhaust manifold fitment — what matters is the engine code, which is tied to the engine designation in the model name rather than the trim grade. An xDrive30d always uses the B57 diesel manifold regardless of trim, and an xDrive40i always uses the B58 petrol manifold regardless of trim, so you do not need to match trim badges. Bear in mind that higher-specification models often have additional heat shielding or sensor positions, so check the manifold's sensor ports match your original before fitting.

Euro 6 compliance on the X7 is achieved partly through the exhaust aftertreatment system (DPF on diesels, catalytic converters on petrols) rather than through the manifold shape alone, but manifolds from different emissions eras can carry different oxygen sensor and temperature sensor ports that are matched to that era's engine management system. If you are sourcing a manifold from a car registered at the Euro 6d boundary (roughly 2019 onwards for the X7), you should confirm with the breaker that the sensor ports and mounting flanges match your specific engine code and registration year. Fitting a manifold with the wrong sensor configuration can cause fault codes or MOT issues, so this is worth double-checking rather than assuming compatibility.

No — petrol and diesel exhaust manifolds on the X7 are entirely different components designed for different engine families and cylinder configurations, and they will not interchange. The diesel B57 inline-six and the petrol B58 inline-six may share a broadly similar engine layout but their manifolds differ in flange design, sensor ports, and fitment points to match each engine's specific characteristics. Always confirm both the fuel type and the exact engine code with the breaker against your registration to ensure you are quoted the correct part.
