MAD BMW S58 Resonated H-Pipe Midpipe M2 G87

The MAD S58 Resonated H-Pipe Midpipe upgrades the sound and flow of your G87 M2 while keeping the factory-style H-pipe layout intact — the right call for drivers who want a deeper, more present note that still stays smooth and refined.

It keeps the OEM dual-pipe configuration, with two pipes merging through a crossover section. Where the factory midpipe uses two secondary catalytic converters and large resonators that choke airflow and dull the tone, the MAD H-pipe swaps in a higher-flowing design — deleting those secondary restrictions and using compact, carefully tuned resonators to clean up the exhaust character.

The result is a real increase in volume and tone without piling on drone or harshness, holding a smooth note right through the rev range.

Features

• Factory-style dual-midpipe H-pipe design.
• Increased exhaust flow with a clean, sporty tone.

What's included

• Full dual-midpipe H-pipe assembly.
