Milltek Sport Resonated Cat-Back Exhaust with Cerakote Black GT-90 Tips for BMW M140i F20/F21 LCI (3 & 5 Door) 2015+ - T304 Stainless Steel, No Drone Performance

Milltek resonated catback with Cerakote black GT90 tailpipes for BMW 1 Series M140i F20 F21 LCI 2015 onwards

Give your 1 Series M140i the soundtrack and style it deserves with this Milltek resonated catback system featuring stealthy Cerakote black 90 mm tailpipes. Designed for the facelift F20 and F21 3 door and 5 door from 2015 onwards, this UK built upgrade delivers a richer, more purposeful tone, stronger throttle response and premium looks, all while remaining comfortable on long journeys thanks to its drone free tuning.

What you will notice

• Refined, sporty sound with zero boom inside the cabin
• Deeper note under load, calm on the motorway
• Stealth black 90 mm tips for an OEM plus appearance
• Smoother, freer breathing system for optimised performance potential

Built to last

Crafted in the UK from austenitic T304 stainless, this Milltek system uses fully mandrel bent tubing to maintain constant diameter through every bend for superior gas velocity. Enlarged pipework helps your turbocharged straight six breathe more efficiently without sacrificing mid range torque. Precision jig manufacturing ensures excellent fitment and alignment, and the heat resistant Cerakote finish on the GT90 tailpipes keeps that stealth look for the long term.

Why this system is a favourite

• Resonated centre section for a civilised everyday drive and a rich tone when you want it
• Ceramic coated black GT90 finishers for a discreet, premium rear end
• T304 stainless throughout for corrosion resistance and durability
• Engineered flow path for reduced back pressure and crisp throttle response
• Designed, developed and hand finished in the UK
• Direct replacement cat back that keeps the factory catalytic converters in place

Fitment

Compatible with BMW 1 Series M140i LCI facelift models:

• F20 5 door 2015 onwards
• F21 3 door 2015 onwards
