BMW X3 M F97 and X4 M F98: the S58 in SUV form, the exhaust system guide
The X3 M F97 and X4 M F98 are BMW M's first compact SUVs, and they share everything that matters: the S58, a 3.0-litre biturbo inline-six with up to 510 hp and 600 Nm. Their factory exhaust reins in this thoroughbred M engine instead of letting it speak. The same ROG valved exhaust fits both; this guide helps you settle on its configuration.

The S58: BMW M's biturbo straight-six in the X3 M and X4 M
The S58 is a 3.0-litre inline-six boosted by two turbos, developed by the M division for its most sporting models. In the X3 M F97 and X4 M F98 from 2019 to 2023, it produces up to 510 hp in Competition form, with 600 Nm. It revs with a liveliness rare for a turbocharged engine and propels these SUVs with astonishing ease.
The X4 M uses the X3 M's underpinnings beneath a more sloping roofline: same chassis, same engine, hence a shared ROG exhaust. It replaces a factory exhaust that filters the S58 far more than it deserves, and lets you dial in its presence with the valves, from an open growl to the restraint of a family SUV. The engine and ECU stay as they left the factory.
How the exhaust on your BMW X3 M F97 or X4 M F98 is put together
An exhaust system is best understood in two parts. Here is what each one does, and what ROG replaces.
The cat-back is the complete exhaust system
It is everything you can see under your BMW X3 M F97 or X4 M F98, from the outlet of the front section to the tips: pipes, silencers, valves. Routing, silencer, valves: this is where the sound is shaped, and where we focus our research and development.
The front section, where the catalytic converter sits
On your BMW X3 M F97 or X4 M F98, it is the downpipe, the pipe leading from the turbo. It contains the factory catalytic converter: the second restriction in the exhaust, after the silencer. Changing this part remains a choice: it pays off mainly with an ECU remap, which turns the freed-up flow into power.
The figures for your BMW X3 M F97 or X4 M F98
What an exhaust changes straight away is the sound, the engine's breathing and the weight at the rear. For more power, add an ECU remap.

Published factory and Stage 2 figures.
With or without an ECU remap, the exhaust fits and works. But it is an ECU remap at an approved tuning centre that truly unlocks your BMW X3 M F97 or X4 M F98, and that is what we recommend.
The S58 has considerable headroom: at Stage 2, both SUVs are quoted at 700 hp and 850 Nm, with a build that must take the transmission and cooling into account. The result remains specific to each car. The ROG exhaust claims no share of this gain; it gives the engine the voice that goes with it.
Configuring your exhaust, step by step
5 choices, in the same order as the product page configurator.
-
Step 1 of 5: Design: the voice of the exhaust
The design changes the tone of your BMW X3 M F97 or X4 M F98. This is the choice that matters most for the sound.
Standard
Included
The raw, direct sound of the twin-turbo S58. No resonator, more volume, more presence. The twin-turbo character comes through in full, unfiltered.
Equal Length
+€250
The lengths of the two pipes are balanced before they merge. The pulses sync up and the note rises in pitch. The S58 sounds like a true inline-six: higher, more even, less raspy. A sound register that completely changes the acoustic identity of the car.
Equal Length + Z-pipe
+€350
A Z-shaped layout that amplifies the crossover of the exhaust flows. The note turns very high in frequency, exotic, close in character to a naturally aspirated Japanese engine at high revs. For drivers who want to take the sound experience to its limit.
-
Step 2 of 5: Material: stainless steel or titanium
For your BMW X3 M F97 or X4 M F98, the exhaust costs €3,990 in stainless steel and €4,990 in titanium.
304 stainless steel
€3,990
- Weight
- Baseline
- Sound
- Full and rounded
Durable, corrosion-resistant, with a rounded, full sound: the most popular option.
Titanium
€4,990
- Weight
- Around 40% lighter
- Sound
- Metallic, crystal-clear
For the same design, it weighs around 40% less than stainless steel. A more metallic note at high revs and a look all of its own, from brushed to blued.
Both materials age well: 304 stainless steel copes with winter and salt, and titanium does not rust. Stainless steel or titanium: what really changes.
-
Step 3 of 5: Front section: downpipe and catalytic converter
Optional: the downpipe on your BMW X3 M F97 or X4 M F98, with its catalytic converter. Sound rating out of 10, valves open: the factory exhaust sits at 3.
Cat-back only
Included
7/10Factory emissions control
Nothing changes at the front: the cat-back alone is already enough to change the car.
200-cell sports catalytic converter
+€970
8/10Road use and inspection
The everyday compromise: emissions control is still there, and breathing improves noticeably.
100-cell sports catalytic converter
+€970
9/10Inspection: depends on local rules
One step further: more flow, a more aggressive sound, reduced emissions control.
Decat
+€700
10/10Track use
Everything unleashed: maximum flow and unrestrained sound, for the track.
Sound intensity, on a scale of 0 to 10
- 10/10Decat downpipe + ROG cat-back
- 9/10100-cell sports catalytic converter + ROG cat-back
- 8/10200-cell sports catalytic converter + ROG cat-back
- 7/10ROG cat-back only, factory catalytic converter retained
- 3/10Factory exhaust, for comparison
Valves open. With the valves closed, every configuration becomes discreet again.
What about the engine warning light? It can appear with a sports catalytic converter: the downstream oxygen sensor reads a different level of cleaning from the factory unit. It is not an engine fault, and it is dealt with by an ECU remap or a diagnostic tool. With a decat, an ECU remap becomes necessary. If it happens to you, call us and we will point you in the right direction. Passing vehicle inspection with a sports exhaust.
-
Step 4 of 5: Valves: ROG remote or factory control
Two ways to control the valves on your BMW X3 M F97 or X4 M F98.
ROG remote
The simplest solution: a control unit in the boot and a remote, open or closed at the press of a button, whatever mode you are in. A question while fitting? We will get back to you.
Factory control
- Only for vehicles fitted with factory valves
- Controlled by the drive modes
Does your vehicle have factory valves? The exhaust keeps their existing control: the drive modes operate the valves, as before, with no added electronics.
On a long journey, what matters is the absence of drone at a steady speed. With the valves closed, the exhaust keeps the cabin calm; the show is still there whenever you ask for it. More about exhaust drone.

BMW X3 M F97 or X4 M F98: your questions
How much power does an exhaust system add to the BMW X3 M F97 or X4 M F98?
As standard, the BMW X3 M F97 produces from 480 to 510 hp; the BMW X4 M F98 produces from 480 to 510 hp. Without a remap, the exhaust transforms the voice and lightens the rear; it is the ECU remap that increases power. The published Stage 2 figures for each model are shown in the figures table.
Stainless steel or titanium: which material for the BMW X3 M F97 or X4 M F98?
For the BMW X3 M F97 or X4 M F98, the ROG exhaust costs €3,990 in stainless steel and €4,990 in titanium. Choose stainless steel for value for money and a rounded sound, titanium to save around 40% in weight and get a clearer tone.
Do you need to replace the catalytic converter on the BMW X3 M F97 or X4 M F98?
No, the cat-back alone already does most of the work on the BMW X3 M F97 or X4 M F98. The downpipe option is for those tuning the engine: 200 cells to stay road-friendly, 100 cells or decat for the track.
Will a ROG exhaust pass vehicle inspection on the BMW X3 M F97 or X4 M F98?
The cat-back only and the 200-cell sports catalytic converter both keep emissions control: that is the configuration to present, with the valves closed. The 100-cell brings more sound and flow, and whether it is accepted at the emissions test depends on the car and local rules; the decat version is intended for track use on the BMW X3 M F97 or X4 M F98.
How is the ROG exhaust fitted to the BMW X3 M F97 or X4 M F98?
Fitting needs no welding or cutting and takes two hours on average on a lift. We check compatibility with the VIN of your BMW X3 M F97 or X4 M F98 before manufacturing.
What does a ROG exhaust cost for the BMW X3 M F97 or X4 M F98, and how long does it take?
From €3,990 to €6,310 depending on the configuration. Allow 20 working days from order confirmation to delivery. Free delivery, 3-year warranty.
Unsure about your configuration? Give us a call.
Stainless steel or titanium, cat-back only or the complete system: the right choice depends on how you drive and on your BMW X3 M F97 or X4 M F98.
