LAB SuperFlow 4.0" Single Midpipe — BMW G8X M3/M4 (2021+)

In Stock • Heat Shielded • Engineered for Maximum Tone, Flow & Clearance

Give your G87 M2 the exhaust tone and flow it deserves with the LAB SuperFlow 4.0" Single Midpipe — designed to deliver a deeper, smoother, and more aggressive sound without sacrificing refinement or practicality.

Compared to standard 3.5” midpipes, the SuperFlow’s 4.0” diameter unlocks a richer low-frequency tone and higher exhaust velocity, transforming the car’s character instantly. And unlike oversized 4.5” systems, it maintains proper ground clearance, avoids scraping, and doesn’t add unnecessary weight.

This is the balance other midpipes miss — maximum sound, maximum performance, minimum compromise.

🔥 Why the SuperFlow Exists

• Deeper, Bolder Sound
  A fuller exhaust note that finally lets the S58 sound like a purpose-built M engine.

• Heat Shielded Construction
  Built for durability, consistency, and real-world use — not just dyno runs.

• Weight-Saving Engineering
  Midpipes should free flow and reduce weight — not add it.

• Built-In Resonators
  Smooth out rasp from downpipes and larger diameters, delivering a clean, exotic tone.

• Zero Scraping, Zero Fitment Issues
  The SuperFlow clears factory ride height and lowered setups — no compromises.
