These large-bore downpipes with catalyst bypass pipes for the S58-powered BMW G87 M2, G80/G81 M3 and G82/G83 M4 are fabricated with a larger diameter than the factory parts and remove the primary catalysts entirely, giving maximum gas flow, significant power gains and a much more aggressive sound.
Please note: This is a de-cat product for off-road/motorsport use only, is not E-marked for road use, and will require an ECU remap. Compatible with the OE GPF sections, or with Milltek 4" or 3" GPF deletes (the OE connection pipe must be re-used to join the 3" deletes).
