BMW Downpipes
Shop BMW downpipes for turbocharged N54, N55, N20, B48, B58, S55, N63, and M57 diesel applications. This collection covers selected BMW 135i, 328i, 335i, 340i, 435i, 535i, M2, M3, M4, X5, X6, and other models. A less restrictive downpipe may improve exhaust flow, support quicker turbo response, and produce a stronger exhaust note. Always verify the engine, chassis, production year, drivetrain, and turbo configuration before ordering.

The model name alone is not enough to confirm fitment. BMW may use different turbo outlets, flange designs, sensor locations, and exhaust connections within the same model range. Before purchasing, confirm your model year, engine code, chassis code, production date, and xDrive or rear-wheel-drive configuration.
