Milltek performance rear system with particulate filter bypass and quad 100 mm matte black ceramic-coated tailpipes for BMW M240i Coupé G42 xDrive (2022 onwards). Part number: SSXBM1224.

Transform the sound and character of your G42 M240i with a premium UK-built system that is all about flow, tone and quality. This precision-made setup replaces the rear section and integrates an OPF/GPF bypass for a sharper, more engaging soundtrack while retaining daily refinement. It bolts on without trimming the factory pipework, so installation is neat and fully reversible. For correct operation you will need suitable Stage 2 ECU calibration or an OPF/GPF bypass controller.
