Milltek Sport Downpipes - 2023-2026 BMW M2 G87 S58

These Milltek Sport parts fit the 2023-2026 BMW M2 coupe (G87) with the 3.0 liter S58 twin-turbo six. For the G87 M2, Milltek offers catted HJS or catless S58 downpipes, plus secondary cat bypass mid-pipes in non-resonated, resonated and X-pipe forms. A Milltek hot-side part replaces the restrictive factory section with larger, smoother T304L tubing, so exhaust gas leaves the engine with less resistance. Pick a catted version to keep a catalytic converter in the system, or a catless version for a dedicated track car. The BMW M2 G87 parts are T304L stainless steel with mandrel-bent tubing, which keeps the pipe at full size through each bend and resists corrosion for years. They bolt in place of the factory parts with no cutting or welding.

Fitment Notes

• Fits the 2023-2026 US-market M2 coupe (G87). The downpipes also fit the G80 M3 and G82 M4.
• Each mid-pipe names whether it joins the factory or a Milltek axle-back.
• The cat bypass sections and 102 mm mid-pipes replace the secondary catalytic converters, while the primary cats stay in the downpipes unless you choose a catless downpipe. No CEL downpipes are designed to avoid a check-engine light. All are race products; catless downpipes need a Stage 2 ECU remap and are for off-road or track use only.
• Catless parts remove the catalytic converter. They are sold for off-road and competition use only and are not legal on public roads in the US.
