BMW S58

The S58 at a glance.

The S58 is BMW M's 3.0-litre twin-turbo straight six, introduced in 2019 on the X3 M F97 and X4 M F98, then on the M3 and M4 G8x and the M2 G87. It displaces 2,993 cc and pairs two single-scroll turbos, one for each group of three cylinders, with a closed deck block and a cylinder head whose core is 3D-printed to channel the coolant more effectively. An engine designed for the track, which handles tuning with ease.

BMW quotes 480 hp and 600 Nm for the X3 M and X4 M (510 hp in Competition form), 480 hp and 550 Nm for the M3 and M4 (510 hp and 650 Nm in Competition form), and 460 hp and 550 Nm for the M2 G87 at its launch in 2023. With a downpipe and a remap, our M3 / M4 G80 and M2 G87 product pages list a Stage 2 at 700 hp and 900 Nm.

Each model also has its own page, with all its options: the M3 / M4 G80, the M2 G87 and the X4 M F98.

The sound of the S58.

As standard, the S58 breathes through a particulate filter and large mufflers, so much so that BMW tops up its sound through the speakers. With the valves closed, the Rog system stays close to the original sound and the cabin remains calm on the highway. With the valves open, the straight six finds its true voice: a dense, metallic edge that pulls all the way to the rev limiter without running out of breath.

What the Rog system changes.

A valved cat-back exhaust that you configure piece by piece:

  • Three designs: Standard, Equal Length, or Equal Length + Z-pipe, the most refined system we make. Standard keeps the raw edge of the twin-turbo; Equal Length gives every pipe the same length, so the exhaust pulses fall into step and the note climbs, smoother and less raspy; the Z-pipe pushes it towards an exotic, high-pitched wail at high revs.
  • Two materials: 304 stainless steel, or titanium, around 40% lighter for the same design, in a brushed, gold or purple finish.
  • Sound character: straight pipe, or a resonator for a rounder, slightly softer voice that stays every bit as sporty.
  • The valves: the system takes your original valves or comes with the Rog valve system and its remote control.

What the downpipe changes.

On the S58, the downpipe is the section that follows the turbos and carries the original catalytic converters. It is the part that restricts the exhaust gases the most: replacing it makes the engine more present and the turbos more audible, and it is what opens the way to power gains, with a remap. Without a remap, it brings sound and less weight, not extra horsepower.

Rog offers it in three versions: 200-cell sports catalytic converter, 100-cell sports catalytic converter, or decat. The 200-cell version keeps emissions control; the 100-cell and decat versions do not. You can order it with the system, in the configuration on your product page, or on its own when it appears in the list on this page.

Frequently asked questions.

Which cars have the S58 engine?

The BMW M3 G80 / G81, M4 G82 / G83, M2 G87, X3 M F97 and X4 M F98, Competition versions included. Rog makes a system for each of them; your VIN, given when you order, confirms compatibility.

Standard, Equal Length or Equal Length + Z-pipe: which is right for the S58?

Standard for a raw, full-bodied sound. Equal Length for a higher-pitched, smoother straight six: it is the option that changes the car's character the most. Equal Length + Z-pipe for the highest, most exotic note.

Does an S58 need a remap after an exhaust or a downpipe?

Not for the cat-back alone: the S58 keeps its original ECU. With the downpipe, a remap is recommended: it is what unlocks the power, and it stops a sports catalytic converter from triggering the engine warning light.

200-cell, 100-cell or decat: which should I choose?

The 200-cell version keeps emissions control and already gives a more present sound. The 100-cell version lets the gases flow more freely. The decat version is the freest flowing and the loudest of the three.

Original valves or the Rog remote?

With your original valves, the BMW's drive modes open and close them, just as before. With the Rog system, the remote opens or closes them at the touch of a button, whatever mode you are in.
