Milltek Sport Race Non-Resonated Cat-Back Exhaust for BMW M140i F20/F21 LCI (2015+) - Cerakote Black GT-90 Tips - T304 Stainless - 3 & 5 Door

Milltek Sport performance rear system for BMW M140i F20 F21 LCI 2015 onwards with black ceramic GT90 90 mm tailpipes

Give your BMW M140i the soundtrack it deserves. This Milltek Sport non-res catback delivers a harder-edged tone, sharper throttle response and a premium stealth look thanks to the black ceramic-coated GT90 finishers. Crafted in Britain from austenitic 304-grade stainless steel with mandrel-bent pipework, it is a direct bolt-on upgrade that fits the facelift 1 Series M140i hatchback in both three-door and five-door form.

Why enthusiasts choose this system

• Non-res layout for maximum volume and character with a purposeful, motorsport-inspired note
• Black ceramic GT90 90 mm outlets for a tough, heat-resistant, stealth aesthetic
• 304 stainless construction for long-term corrosion resistance and durability
• Free-flowing, mandrel-bent tubing to reduce back pressure and complement future tuning
• TIG-welded and precision engineered in the UK for consistent fitment and quality
• Sits after the catalytic converter for a straightforward, bolt-on upgrade using factory mounts
• Designed to enhance the B58 turbo six soundtrack without excessive cabin boom at cruise

How it sounds and feels

Expect a deeper idle, a richer tone through the revs and an aggressive rasp under load. On the motorway it settles into a refined hum, while around town it brings the M140i’s B58 character to life. The black GT90 finishers complete the rear end with an OEM-plus look that does not shout until you want it to.

Compatibility

• BMW M140i F20 LCI 3-door, 2015 onwards
• BMW M140i F21 LCI 5-door, 2015 onwards
