The S55 is a legendary inline-six. The factory midpipe keeps it from sounding like one.

The F80-generation M3 and M4 defined an era — and at the heart of each one sits the S55, a twin-turbo inline-six with serious character. But between the turbos and the tailpipes, the factory mid section does what factory mid sections always do: it smooths out the pulse, muffles the voice, and adds weight while it's at it.

The Fupower equal length Z-style midpipe changes that equation. Equal-length runners, Z-style routing, and SS304 stainless steel construction — precision-built to let the S55 speak with the clear, even inline-six voice it was born with.

Engineered for the **2021+ BMW G80 M3, G82 M4 with S58 3.0L turbo engine**, our Equal‑Length Z‑Style Midpipe unlocks true exhaust performance while refining the factory exhaust tone. The stock mid‑section suffers from uneven exhaust gas pulses between cylinder banks, causing inconsistent scavenging, turbo lag and harsh exhaust notes under heavy acceleration. Our newly developed Z‑style equal‑length midpipe fixes these factory limitations with precision‑engineered geometry.
