S58 Midpipe — BMW M2 / M3 / M4 / X3M / X4M (Choose Your Configuration)

Details

Build Your Sound. Z-Pipe, X-Pipe, H-Pipe & More.

The mid-section is where your S58's character is decided. Pick the configuration that matches the sound you want — from a clean resonated single to a full Z-pipe screamer. All T304 stainless, mandrel-bent, fully welded, and built as a direct bolt-on.

Choose your config:

• Single Non-Resonated — loudest single, most aggressive, raw tone. The budget-friendly volume button.
• Single Resonated — big sound with the worst of the drone tuned out. Great daily balance.
• X-Pipe — exotic, raspy high-RPM howl with even cylinder blending.
• H-Pipe — deeper, muscle-car rumble and broad mid-range.
• Z-Pipe — our signature: maximum volume, sharpest tone, full character. Top of the range.
