Milltek Sport Cat-Back Exhaust - 2023-2026 BMW M2 G87

This Milltek Sport cat-back exhaust fits the 2023-2026 BMW M2 coupe (G87) with the 3.0 liter S58 twin-turbo six. For the G87 M2, Milltek offers a non-resonated system from the secondary cats back, plus full cat-backs that replace the secondary cats, non-resonated or resonated, each with GT-115 tips in five finishes. Each system is built for this exact chassis, so it follows the factory routing, hangs from the stock mounts and keeps the ground clearance of the original exhaust. Compared with the factory steel parts it is lighter, flows more freely and gives the engine a clearer, stronger voice under load, without the harsh highway drone of a cheap straight pipe. 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. It bolts on with the factory hangers and clamps, with no cutting or welding needed. It swaps the factory exhaust from the catalytic converters back, using 76.2 mm (3 in) T304L stainless steel pipework, and bolts to the factory mounting points.

How to Choose

Start with the System. Secondary Cat-Back, Non-Resonated (Louder) runs from the factory secondary cats back with no resonators, a louder note that keeps every factory cat. Cat-Back, Non-Resonated (Loudest) replaces the secondary cats too, with no resonators: the loudest option. Cat-Back, Resonated (Quieter) replaces the secondary cats and keeps a resonator for a deeper tone with less drone.

Then pick an Exhaust Tip Finish: Polished (bright polished stainless), Cerakote Black (a black Cerakote ceramic coating), Brushed Titanium (a brushed titanium finish), Carbon Fiber (carbon fiber outer sleeves), Burnt Titanium (a heat-blued burnt titanium finish). The finish changes the look only, not the sound.

The Add Downpipe option bundles a Milltek downpipe with the cat-back. No Downpipe keeps your factory downpipe. Catless Downpipe has no catalytic converter. It is for off-road and track use only and needs an ECU remap. Catted Hi-Flow Sports Cat Downpipe keeps a high-flow sports catalytic converter. Milltek recommends an ECU remap with it. You can also buy them on their own from the downpipes for the BMW M2 G87.

Fitment Notes

• Fits the 2023-2026 US-market BMW M2 coupe (G87).
• The secondary cat-back keeps the factory secondary catalytic converters and is not a race product. The full cat-backs replace the secondary cats; the non-resonated one is a Milltek race product for off-road or track use.
• The downpipe add-ons are race products and need an ECU remap; the catless version is 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.
