High‑flow centre exhaust section for BMW F8X

Unlock a richer, smoother soundtrack from your S55 with this 3.5 inch single centre pipe designed for the BMW F8X platform. Crafted from T304 stainless steel, this upgraded mid section replaces the secondary catalytic converters and links directly between the downpipes and the factory rear silencer for a transformative sound and flow boost.

What you’ll notice

  • Deeper, more refined exhaust note with reduced metallic rasp on the F8X chassis
  • Improved exhaust flow thanks to a large 3.5 inch single centre pipe
  • Keeps the OE back box and valve control while elevating the overall tone
  • Durable T304 stainless construction for long‑lasting performance

Fitment

Engineered for the BMW M3 and M4 F8X series, including:

  • M3 F80 saloon
  • M4 F82 coupé
  • M4 F83 convertible

Intended to sit between the downpipes and the standard rear section. Please note: cutting of the factory exhaust is required to install with the OEM back box.

Why enthusiasts choose this centre pipe

This 3.5 inch centre section is a proven upgrade for owners seeking a fuller tone without excessive volume. We’ve run this setup on our own cars and customer builds, and feedback has been consistently positive: smoother midrange, cleaner top‑end sound and less undesirable rasp when paired with freer‑flowing hardware.
