BMW M3 G80 / M4 G82 G83 2020–2023 S58 Stainless Steel Exhaust Manifold

Product overview

This stainless steel exhaust manifold is listed for the BMW S58 3.0-litre twin-turbo straight-six found in the M3 G80 and M4 G82 and G83 from 2020 to 2023, with the listing also naming the M2 G87. It is fabricated from 304 stainless steel with a mirror-polished finish, using TIG welding and CNC machining. It is aimed at enthusiasts and workshops replacing or upgrading exhaust components on these performance models.

Polished stainless steel also provides a striking under-bonnet appearance.

Vehicle compatibility

The listing names BMW M3 G80, M4 G82 and G83 (2020–2023) and M2 G87 with the S58 engine. The fitment rows attached to the listing refer to the BMW 340i from 2016 to 2018, which uses a different engine, and the part listing mentions unrelated makes. Fitment is therefore partial and must be confirmed before purchase.

Key features

• 304 stainless steel construction for heat and corrosion resistance
• 1.5 mm material thickness, as stated by the listing
• TIG-welded joints and CNC-machined flanges
• Mirror-polished silver finish
• Single inlet design as listed

Technical specifications

Installation requirements

Exhaust manifold replacement on the S58 is an involved job requiring turbocharger access and new gaskets. We recommend installation by an experienced performance workshop. Check all joints for leaks once the engine reaches operating temperature. Modified exhaust components may affect emissions and noise compliance, so check Australian and New Zealand requirements before fitting.

Allow the system to go through several heat cycles, then recheck fastener tightness.

Fitment checks before ordering

Because listing data conflicts between the S58 M models and the 340i, please confirm your engine code, model and VIN with us before ordering. We will verify the correct manifold design for your car.
