Frequently asked questions
Will these systems fit both the RWD and xDrive models?

Yes, our range of exhausts from Akrapovič, Milltek, and Remus are engineered to fit both the Rear-Wheel Drive and xDrive variants of the G42 M240i and 230i.
Does an "OPF-Back" system require an ECU remap?

No. An OPF-Back (or GPF-Back) system replaces the exhaust components after the particulate filter. This means you get a significant increase in volume and tone without affecting emissions sensors or requiring any software changes.
How much weight can I save with a Titanium system?

Switching to an Akrapovič Titanium Slip-On system can save approximately 4kg to 9kg compared to the stock stainless steel unit. This reduction in weight at the very rear of the car helps improve the G42's already impressive handling balance.
Do valved exhaust systems work with the factory modes?

Yes. Many exhausts for the G42 M240i integrate with the car’s factory driving modes, letting you switch between a quiet cruise and a louder performance sound with ease.
What exhaust systems are available for the BMW G42 M240i?

You can choose from cat-back systems, axle-back exhausts, and valved performance exhausts, all designed to fit the G42 chassis perfectly. Brands such as Akrapovič, Milltek and Remus offer engineered solutions tailored to this model.
