Fabspeed's valved exhaust for the G80 M3 and G82 M4 is a plug-and-play replacement for the restrictive, quiet factory system. It is designed around the S58 to improve scavenging and cut back pressure, and it is built in-house at Fabspeed's facility in Pennsylvania.

What you get

  • Valved exhaust system with Helical valves sourced from the UK, chosen to avoid valve failures.
  • More tone, volume and power than the OEM exhaust.
  • Hand-built in the USA at Fabspeed's Pennsylvania shop.
  • Four tip finishes: satin black, carbon fiber, polished or titanium.
