Milltek Sport Cat-Back Performance Exhaust - Race Non-Resonated, Polished GT-90 Tips - BMW M140i F20/F21 LCI (2015+) 3 & 5 Door

Milltek Sport performance rear section for BMW M140i F20 F21 LCI 2015 onwards with mirror-finish 90 mm GT90 tailpipes

Give your BMW 1 Series M140i the soundtrack it deserves with this UK-made Milltek Sport system. Crafted from high-grade 304 stainless with precision mandrel bends and a straight-through, non-silenced layout, it unlocks a deeper, louder, motorsport-inspired tone while keeping everyday drivability intact. The polished 90 mm GT90 outlets sit perfectly in the facelift F20 and F21 bumper cut-outs for a purposeful OEM plus look.

Key reasons enthusiasts choose this upgrade

• Premium 304 stainless construction for long-lasting durability and corrosion resistance.
• Free-flow pipework to reduce backpressure and sharpen throttle response on the B58 turbocharged 3.0 engine.
• Non-res layout for an aggressive, track-style note and increased volume compared to stock.
• CNC mandrel bends and high-quality welds for consistent flow and a refined finish.
• Polished GT90 twin outlets for a clean, bold rear-end appearance.
• Designed to bolt to factory mounting points for a precise, hassle-free install on facelift F20 and F21 hatchbacks.

What it feels and sounds like

Expect a stronger cold start bark, richer tone through the rev range and a crisp top-end without unwanted boom. On the road it adds excitement and character to the M140i while remaining civil at cruise. We have fitted and used this system ourselves, and our customers consistently report superb fitment, quality and a grin-inducing soundtrack.
