Upgrade the exhaust note of your BMW M135i (F20/F21) with this Milltek Sport Road Rear Silencer. Available in three tip finishes, this EC-approved rear silencer is a direct replacement for the OEM rear box, delivering a notably more aggressive exhaust note with improved sound quality — all whilst retaining the refinement expected from a road-going system.
The Milltek rear silencer is engineered to work in harmony with the OEM front sections and catalysts, meaning no additional modifications or remapping are required. You'll notice the improved character immediately, particularly at higher revs, whilst cruising noise remains composed and comfortable. Choose from Polished, Cerakote Black, or Titanium tip finishes.
