Frequently asked questions
Do these exhausts fit the rear-wheel-drive M240i or the 230i?

The systems here are listed for the M240i xDrive. None of the product pages lists the rear-wheel-drive M240i or the 230i, so if that's your car, ask us before you order.
Does an OPF-back exhaust need a remap?

Milltek's particulate filter-back system keeps the factory filter, and its listing doesn't call for coding or a remap, although fitting it means cutting the original exhaust at the connection point. The Milltek cat-back system and OPF/GPF bypass do need vehicle coding, Stage 2 ECU software or an OPF/GPF bypass module.
Which M240i exhausts are road legal?

Milltek lists its particulate filter-back system as proposed ECE approved, and Remus offers EC-approved axle-back and cat-back systems. The Milltek cat-back, OPF/GPF bypass and downpipe and decat, and the Remus racing versions without EC approval, are listed for off-road or track use.
Can I control the exhaust valves on the M240i?

Milltek's Active Valve Control Plug & Play System lists the M240i xDrive Coupé, OPF and non-OPF. It gives remote control of the valves on the factory exhaust or a Milltek system, with no cutting or coding.
What does fitting a G42 exhaust involve?

It depends on the part. Milltek's particulate filter-back system means cutting the original exhaust at the connection point, and Milltek recommends professional fitting. The Remus systems come as axle-back or cat-back sections with mufflers, quad tips and mounting hardware, and the Milltek valve control module plugs in. If you'd like us to fit it, contact our team.

Exhausts and exhaust parts for the BMW M240i xDrive Coupé (G42) from Milltek Sport and Remus.

Milltek's range covers a particulate filter-back system, a cat-back system, a catback for non-OPF North American cars, an OPF/GPF bypass, a large-bore downpipe and decat, and plug-and-play valve control. Remus offers axle-back and cat-back systems, with and without EC approval.

Every system here is listed for the M240i xDrive. Several parts, including the Milltek cat-back, the OPF/GPF bypass and the downpipe and decat, are listed for off-road use only, and each product page says which.
