Milltek Sport rear system for BMW M140i F20 F21 LCI with PPF/OPF – silenced, Cerakote black 90 mm GT outlets

Upgrade the soundtrack and style of your BMW 1 Series M140i with this UK-built Milltek Sport rear section that runs from the particulate filter back. Designed specifically for facelift F20 and F21 cars fitted with the petrol particulate filter from 2019 onward, this silenced setup delivers a deeper, more refined tone on the B58 straight-six while keeping everyday manners intact. The stealthy Cerakote black 90 mm GT tailpipes complete the look with a premium, motorsport-inspired finish.

Why this upgrade stands out

• Direct bolt-on rear section that works with the factory OPF/GPF, enhancing sound without removing emissions hardware.
• Silenced configuration for zero drone on the motorway and a mature note when cruising, with a sporty growl under load.
• Cerakote black coated 90 mm GT tips for a durable, heat-resistant, low-gloss appearance that suits the M140i’s rear bumper perfectly.
• Crafted from 304-grade stainless steel for exceptional longevity and corrosion resistance.
• Mandrel-bent tubing to maintain consistent internal diameter for smooth gas flow and crisp throttle response.
• Acoustically developed to avoid unwanted cabin resonance while unlocking that classic straight-six character.
• Hand finished in Britain for precise fitment using original mounting points.

• BMW M140i hatchback, 3-door and 5-door
