What holds back the factory sound
The B48 has a dry, surprisingly gravelly voice, but the factory exhaust of the X1 keeps it to itself.
What the Rog exhaust changes
With the Rog exhaust and the valves open, the gravelly grain of the engine comes through every time you get back on the throttle; with the valves closed, the X1 is once again the everyday family SUV. The engine and its ECU stay factory.

Your VIN, entered when you order, confirms the version before manufacturing; the X1 F48, the previous generation, has its own guide.
Closely related versions have their own guide: BMW X1 B48 F48 2.0T, BMW 230i B48 G42 2.0L.
Choosing your exhaust.
Four decisions, in this order: each one builds on the one before, and the last no longer affects the sound. Before you start, here is what you are buying.
Your exhaust: the cat-back
The cat-back is the complete exhaust system
Everything you see under the car, from the outlet of the factory catalytic converters to the tips: pipes, silencers, valves. It is what creates the sound. The factory front section, catalytic converters included, stays in place: the exhaust connects behind it.
-
Step 1 of 4: Sound: the voice of your car
On this car, the sound is shaped in two places: the character of the exhaust, presented here, and the volume of the moment, which you set with the valves (step 3). The front section, for its part, stays factory.
The character
At the same price, two characters: the straight pipe, to hear the raw sound of the engine, unfiltered; the resonator, for a rounder, slightly softer voice. With either one, the exhaust stays fully sporty.
Pure · straight pipe
Same price
Round · resonator
Same price
Our advice. The straight pipe if you want to hear your engine unfiltered, the resonator if you prefer a rounder voice. Exhaust resonator: what does it do?.
-
Step 2 of 4: Material: stainless steel or titanium
The material changes three things: weight, sound and durability. It is a genuine technical choice, not just a matter of looks.
304 stainless steel
Base price
- Weight
- Baseline
- Sound
- Full and rounded
- Durability
- Withstands salt and winter
Tough, corrosion-proof, with a full, rounded sound. The choice of most of our customers.
Titanium
Optional
- Weight
- Around 40% lighter
- Sound
- Metallic, crystal-clear
- Durability
- Does not rust
Around 40% lighter than stainless steel for the same design, with a more metallic sound that turns crystal-clear at high revs. You then choose it in one of three colours, at the same price (step 4).
Our advice. Stainless steel for a first purchase and everyday use; titanium if you are chasing every kilo and want a higher-pitched note at high revs. Over time, both last. Stainless steel or titanium: what really changes.
-
Step 3 of 4: Valves: our remote or your factory valves
The valves set the volume at every moment: closed, the gases pass through the silencer and the car keeps a sound close to the factory one; open, they take the shortest route. All that remains is to choose who controls them.
Rog system and remote
Included
The exhaust comes with our valves fitted and a two-button remote, open and closed; a small control unit fits in the boot. The valves stay in the position you choose, whatever the drive mode: open, they stay open; closed, they stay closed.
Your factory valves
Included
- If your car has factory valves
- Controlled by the drive modes
If your car has factory valves, we deliver the exhaust with mounting points for them: your garage refits your valves there, and everything works as before, through the drive modes.
Valves open, valves closed: the path the gases take through the silencer. Our advice. The remote if you want to decide for yourself, at any time; your factory valves if you value the standard drive modes. For inspection, present the car with the valves closed. On track, open them: that is where they come into their own.
On the motorway, with the valves closed, all the exhaust flow passes through the silencer, designed for long distances: no drone at a steady speed. You open up when you feel like it, not when the motorway decides for you. Why our exhausts stay calm on the motorway.
-
Step 4 of 4: Looks: titanium colour and tips
The last step, and the freest. The titanium colour and the tips are purely aesthetic choices: they change nothing about the sound or the performance of the exhaust. Choose them with your eyes.
The titanium colour
Three colours, at the same price: brushed, gold or purple. They only apply to titanium; in stainless steel, the exhaust keeps the colour of the steel.
Brushed 
Gold 
Purple The tips
Rog tips in chrome, gloss black or blued titanium, included in the price, or carbon tips with the M logo, as an option: forged carbon, black carbon or carbon and titanium. You can also order the exhaust without tips.
Chrome 
Gloss black 
Blued titanium 
Forged carbon 
Black carbon 
Carbon and titanium
Your choices carry over to the product page: only the finishes, your VIN and the cart remain.
Three set-ups, three uses.
If you are still unsure, start from how you use the car: here are the three set-ups we recommend most often for your car.
-
Everyday
- Stainless steel
- Rog remote
Your car finds its voice, the factory emissions control stays in place, and you open the valves when you decide.
View this configuration -
Lighter
- Brushed titanium
- Rog remote
An exhaust around 40% lighter than stainless steel, and a more metallic note as the engine climbs through the revs.
View this configuration -
Style
- Gold or purple titanium
- Gloss black tips
The colour makes no difference to the sound: it is the car's signature. In gold or purple, with gloss black tips, the exhaust is seen as much as it is heard.

Questions.
What does an X1 M35i U11 sound like with a Rog exhaust?
With the valves closed, the car stays close to its factory sound. With the valves open, the engine takes on a full, sporty voice: 7 out of 10 on our scale, compared with 3 for the factory exhaust. Here, everything happens in the exhaust and its valves, as the front section stays factory.
Straight pipe or resonator: which one should you choose?
The straight pipe keeps the engine's raw grain; the resonator rounds off the voice and softens it slightly. Both are the same price, and on our 0 to 10 scale the score does not change: the resonator works on the tone, not the volume.
Which X1 models are covered?
The X1 M35i xDrive U11, built since 2023. The X1 F48 has its own guide; for any other X1, send us your VIN.
Does the X1 M35i gain power with the exhaust?
No, and we do not claim it does: the exhaust changes the voice and the weight, and the engine keeps its 300 hp. For this model, the front section is not offered.
Can you pass vehicle inspection with a Rog exhaust on an X1 M35i U11?
Present the car with the valves closed: it returns to a sound level close to factory. The exhaust fits behind the factory front section: the catalytic converters stay in place and emissions control does not change.
Factory valves or Rog remote?
With your factory valves, it is the car, through its drive modes, that decides. With the Rog system, a two-button remote opens or closes them at any time, and they stay in the position you choose.
Does the exhaust drone on the motorway?
No. With the valves closed, the gases pass through the whole silencer, and at a steady speed the cabin stays calm: our exhausts are designed to avoid that drone. You open up when you decide.
How is the Rog exhaust fitted on an X1 M35i U11?
By your garage, with no welding or cutting: clamps, gaskets and around two hours on a lift are all it takes. The parts arrive ready to fit, with their fixings.
How long does it take to receive a Rog exhaust for an X1 M35i U11?
Allow 20 working days from order confirmation to delivery, the time it takes to make your exhaust. Delivery is free and tracked from dispatch.
What warranty comes with a Rog exhaust for an X1 M35i U11?
3 years, parts and workmanship, from the date of purchase. As for the BMW warranty: in Europe, a manufacturer cannot refuse it simply because a part from another brand has been fitted; it has to prove that the fault comes from that part.
