Let the S58 soundtrack take a bigger role in driving your X3 M. This non-resonated Milltek downpipe-back is the more vocal configuration, with twin 80 mm pipework and five tip finishes. Choose it for the matching pre-LCI GPF or LCI non-GPF ROW/US application. On the pre-LCI GPF car it bypasses the filters, requires Stage 2 software and is for track use.

For owners who want to hear the difference
The non-resonated layout is for a driver who wants more exhaust presence than the resonated equivalent. Choose the matching front configuration first: the pre-LCI GPF application removes the filters, while the LCI ROW/US application is for the compatible non-GPF car. The correct front sections make the louder rear exhaust part of a complete, matching installation.
Which version would we choose?
Choose it when a louder note is the reason for upgrading. For a pre-LCI GPF car where you prefer more silencing, the resonated downpipe-back option is the closer alternative. For a road car retaining the GPF, start with the OPF-back product.
What you get
Non-resonated front replacement section, centre and connecting pipes, valved links, rear silencer, outlet pipes, selected tips and fitting hardware.
Fitting and ownership
The GPF-bypass application requires Stage 2 software. The front section and emissions configuration must match the car: this product does not give blanket compatibility with every LCI X3 M or with the X4 M.

Questions before you order
Frequently asked questions
Does it keep the particulate filters?
No. This configuration bypasses the filters on the GPF application and is intended for motorsport use.
What changes between the five finishes?
The tip material or finish changes; the underlying exhaust configuration stays the same. Brushed and burnt titanium options are titanium tips on a stainless exhaust, while carbon is the tip finish rather than the material of the complete system.
Do I need a remap?
Stage 2 software required for GPF bypass. Arrange any required calibration with the installation.
Will different tips change the sound?
The finish changes the appearance of the tips. It does not change the underlying exhaust configuration shown in the option table.
How should I look after it?
Let the exhaust cool before cleaning. Wash road salt and dirt from the tips regularly with a soft cloth and a non-abrasive cleaner suitable for their finish. Have any new rattle checked for loose fittings or contact with the bodywork.
Fitment first
Check fit before you order
Model year, engine, drivetrain, hardware and existing modifications can all change what fits. Check the applications and supplier notes above, or send us your exact vehicle and setup before ordering.
