Cheap BMW M4 Exhaust Manifold

Yes, the BMW M4 does have exhaust manifolds — one on each bank of its twin-turbocharged inline-six engine (S55 on the F82 generation, S58 on the G82 generation), and sourcing a used one from a breaker is a legitimate route. Because the turbos sit close to the engine, the manifold and turbo housing are tightly integrated in design, so make sure you and your breaker are clear on exactly which component you need. Never guarantee fitment without confirming the part matches your specific engine code and generation.

No — the F82 M4 (2014–2020) uses the S55 engine and the G82 M4 (2021 onwards) uses the entirely different S58 engine, so the manifolds are not interchangeable between generations. These are distinct engines with different architectures, turbo configurations, and mounting points, meaning a part from one will not fit the other. Always confirm the exact generation and engine code with your breaker before ordering.

For the exhaust manifold itself, the Competition trim does not use a different unit — both standard and Competition variants within the same generation share the same engine code (S55 on F82, S58 on G82), so trim level does not affect manifold fitment. You may find cosmetic differences in surrounding components if the Competition had different exhaust tips or rear valance trim, but the manifold itself is not trim-specific. Confirm the engine code with your breaker rather than relying on the trim name alone.

The F82 M4 ran from 2014 to 2020 and received mid-life updates, but the core S55 engine architecture — and with it the exhaust manifold design — remained consistent throughout the generation. In practice, manifolds from across the F82 production run are generally considered the same engine family, but small running changes to emissions calibration or ancillary fittings can occur. Confirm the exact build year and engine code with your breaker to be safe rather than assuming any F82 manifold will be a straight swap.

Yes — both the rear-wheel-drive and xDrive G82 M4 variants use the same S58 engine, so the exhaust manifold is the same regardless of drivetrain configuration. The xDrive system affects the drivetrain below the engine, not the top-end exhaust components. Confirm the engine code matches with your breaker, but drivetrain should not be a barrier here.

The manifold itself is not an emissions device, so swapping like-for-like within the same engine generation does not typically create MOT issues on its own. However, because the M4's manifold sits very close to catalytic converter and emissions hardware, breakers sometimes supply these as an assembly, and that is where Euro 5 and Euro 6 compatibility and cat specifics become important. You should confirm with your breaker exactly what is included in the part and whether any emissions components attached to it match your registration's requirements.
