Description
Give your S58-powered BMW X3M or X4M a more aggressive exhaust character with the MAD 3.5-Inch Non-Resonated Single Midpipe, designed for enthusiasts looking to maximize exhaust volume and create a louder, more pronounced exhaust note.
Specifically engineered for the BMW F97 X3M and F98 X4M, this midpipe replaces the factory center section, removing the OEM secondary catalytic converters and factory resonator and replacing them with a larger 3.5-inch single exhaust pipe. The result is a less restrictive center section designed to improve exhaust flow while significantly changing the sound of the S58 exhaust system.
Unlike the MAD resonated version, this configuration uses a completely non-resonated design. By eliminating the resonator, the system allows more of the engine's natural exhaust character and volume to come through. This makes it an ideal choice for drivers who want a louder and more aggressive exhaust setup, particularly those looking for maximum sound while retaining their factory downpipes.
The larger 3.5-inch single-pipe configuration opens up the center section of the exhaust and provides a more direct path for exhaust gases. This design is intended to improve exhaust flow compared with the factory midpipe while giving the X3M or X4M a deeper and more aggressive exhaust presence under acceleration.
The MAD Non-Resonated Single Midpipe can be paired with factory or aftermarket downpipes and is compatible with the OEM exhaust or suitable aftermarket axle-back systems. This makes it a versatile option for both stock-downpipe vehicles and more extensively modified S58 exhaust setups.
For enthusiasts who prioritize maximum exhaust volume and aggressive sound, the MAD 3.5-inch Non-Resonated Single Midpipe offers a straightforward way to transform the exhaust character of the F97 X3M or F98 X4M.

Exhaust Sound & Performance
The MAD 3.5-inch Non-Resonated Single Midpipe is designed for customers who want maximum sound from their S58-powered X3M or X4M.
Removing the factory resonator allows the exhaust system to produce a louder and more aggressive tone than the resonated version. Combined with the larger 3.5-inch single-pipe configuration, the system opens up the center section and is designed to provide improved exhaust flow compared with the OEM setup.
This configuration is particularly well suited to enthusiasts who are running factory downpipes but want a substantial increase in exhaust volume, as well as those building an aggressively tuned exhaust system where maximum sound is the priority.
