Fix the sound BMW left uneven.

From the factory, the S58’s twin-turbo layout routes exhaust gases unevenly. The front turbo’s exhaust path is significantly longer than the rear, causing the gases to merge out of sync. The result? The raspy, unbalanced tone many G8X owners notice and dislike.

Our Equal Length Midpipe corrects this by equalizing exhaust flow before it reaches the axleback. By matching exhaust gas timing, the engine is finally allowed to sound the way it naturally should.  Smooth, higher-pitched, and far more refined.

What to expect:

  • Cleaner exhaust note with reduced rasp

  • Smoother, more refined tone throughout the rev range

  • Designed specifically for the G8X S58 platform

Build & Fitment Details:

  • Made-to-order with a typical 4–5 week lead time from ordering to delivery

  • Includes all stainless steel hardware

  • Bolts directly to the factory axle-back

  • Cutting required for installation

  • Exhaust clamps included to ensure a clean, straightforward install

Designed specifically for the G8X S58 platform, this midpipe doesn’t add artificial sound, it restores balance. 

Engineered for flow.
Tuned for sound.
