The GOLIATH is Active Autowerke's race-only cat-back for the G80 M3 and G82 M4. It is built around a single mid-pipe and skips the factory valves entirely, so the exhaust is always open. The result is a much deeper and much louder tone than stock, aimed at track cars rather than daily drivers.

What you get

  • Full cat-back built for the track. Based on Active Autowerke's single mid-pipe design.
  • Always-open layout. There are no OEM valves, so there is no quiet mode.
  • Deeper tone than the factory exhaust.
  • Two configurations. Choose the race exhaust alone, or the race exhaust with a dump placed right after the downpipes for even more sound.
  • Four tip finishes: brushed, matte black, carbon, or carbon over black chrome.

Good to know

  • Active Autowerke sells this part for race and off-road use only.
  • It is loud by design and not meant for street use.
