Milltek Sport GPF-Back Cat-Back Non-Resonated Race Exhaust, Burnt Titanium GT-90 90mm Tips - BMW M140i F20/F21 LCI OPF/GPF Only (3 & 5 Door) 2019+

Turn up the character of your B58-powered 1 Series

Give your BMW 1 Series M140i LCI the soundtrack and presence it deserves with this British-built GPF-back race system. Engineered for OPF-equipped facelift models from 2019 onward, it swaps the factory compromise for a sharper, more engaging tone and a purposeful rear-end look thanks to twin 90 mm GT-90 heat-treated blue tips.

Built to perform, made to last

Crafted in the UK from high-grade T304 stainless steel, this backbox and pipework upgrade uses smooth-radius CNC bends and free-flow tubing to reduce restriction and let the B58 turbo straight-six breathe. Weld quality and fit are excellent, using the original hangers for an easy bolt-on installation. The non-res race layout delivers a hard-edged, track-inspired note on throttle while retaining the factory particulate filter.
