The BMW X3 G01 2.0T exhaust in detail.
Spacious, efficient and pleasant to drive, the X3 G01 is BMW’s versatile family SUV. In petrol form, it receives the B48, a 2.0-litre four-cylinder from the modular family, with a twin-scroll turbo and Valvetronic. On this SUV, power ranges from 184 hp and 290 Nm for the xDrive20i to 252 hp and 350 Nm for the pre-facelift xDrive30i, the facelifted mild-hybrid version going back to 245 hp. G01s produced from 2019 to 2024 are covered, while the M40i and the X3 M refer to other pages.
Unleashed, a B48 produces a deep, grainy sound with turbo whoosh in the background; in the stock X3, that character disappears behind a heavily filtering exhaust and careful sound insulation, and what you mostly hear is road and wind noise. With the valves open, our cat-back gives a clear presence at start-up and a gruffer note under acceleration that adds body to overtakes; with the valves closed, the SUV stays welcome for early-morning departures.
A recent X3 does not have to undergo any cutting: its garage connects the exhaust, bent to match the VIN, in a morning, and keeps the drive modes in control of the factory valves, the Rog remote serving cars that have none.
Under the “Manifold” option, the page sells the B48’s downpipe; on its own, it only enriches the voice and saves a little weight, the power coming from a map. On the catalytic side, the hierarchy is clear: 200 cells for an X3 that keeps its stock emissions control, 100 cells accepted or not depending on the car and the rules in your country, decat version reserved for track use. As for the cat-back, 304 stainless steel is enough for most families, with titanium lightening the rear by around 40%.

Questions about the BMW X3 G01 2.0T exhaust.
xDrive20i or xDrive30i, pre- or post-facelift: the same exhaust for the X3 G01?
Our page groups all these versions under the 2019 to 2024 X3 G01 2.0-litre, without listing them individually; your VIN lets us confirm yours before manufacturing.
How much horsepower can an X3 G01 gain in Stage 2?
The page publishes 310 hp and 480 Nm for the 252 hp xDrive30i, and 290 hp and 450 Nm for the 184 hp xDrive20i, with downpipe and ECU remap; no figures are published for the facelifted mild hybrid versions.
BMW X3 B48 G01 2.0T with a Rog exhaust: what should you know about vehicle inspection?
With the cat-back only or the 200-cell sports catalytic converter, emissions control is retained: present the car 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.
Will the X3 G01’s driving modes continue to operate the valves?
As long as your X3 was delivered with factory valves, Eco Pro, Comfort and Sport keep their role; an example without them receives the Rog remote, which works independently of the programme.
A family SUV with a valved exhaust: is it compatible with children on board?
Absolutely: closed valves make the X3 as calm as on delivery, and you only open them once you are alone, on the road of your choice.
BMW X3 G01 2.0T: Does a valved exhaust system drone?
No. With the valves closed, the gases flow through the whole rear silencer and the cabin stays calm at a steady speed. Our Rog exhausts are designed to avoid drone. Learn more: Why our systems stay calm on the motorway.
BMW X3 G01 2.0T: straight pipe or resonator?
On this model, two characters at the same price: the straight pipe for the raw sound of your engine, unfiltered, or the resonator for a rounder and slightly softer voice. Either way, the exhaust stays fully sporty. Learn more: Exhaust resonator: what does it do? Straight pipe or resonator, which sound to choose.

The MOT and your exhaust
At the MOT, exhaust noise is judged by ear, with no sound meter: valves closed, your car sounds very close to stock. A cat-back leaves your factory cat and sensors untouched, a 200-cell sports cat keeps emissions control, and the MOT tester decides.
On the road
Valves closed around town, your car sounds very close to stock, and you open them whenever you like. Where councils use noise cameras, they target behaviour such as revving and racing.
Your documents
Each system is built from the VIN on your V5C, and an exhaust isn't one of the changes you record on it. We send the technical documentation free on request, for the MOT or for your insurer.
Your insurance
Insurers usually want to know about modifications, so let yours know: our free technical documentation makes it easy.
