Milltek Cat-back GPF Back Non-Resonated Race with Titanium GT-90 Trims for BMW M140i F20 F21 LCI OPF 2019 onwards

Upgrade your BMW M140i exhaust with the Milltek Sport Cat-back GPF-back Non-Resonated Race system with Titanium GT-90 trims. Handcrafted in the UK from aerospace grade type 304 non-magnetic stainless steel, this performance exhaust is engineered for durability, corrosion resistance and a sharper, sportier soundtrack. It is designed specifically for OPF models only and fits both 3 Door and 5 Door F20 and F21 LCI cars from 2019 onwards.

This Milltek GPF-back exhaust retains the factory OPF/GPF and catalytic converters while freeing up gasflow from the particulate filter backwards. Mandrel-bent pipework and optimised bore sizing work together to reduce restriction compared to stock, delivering a crisper throttle response and a more engaging drive. The Non-Resonated Race configuration maximises volume and character for a louder, more aggressive tone, developed to be sporty and crisp without unwanted drone or cabin resonance.

We run Milltek systems on our own cars and our customers consistently rate the fit, finish and sound quality. The Titanium GT-90 trims complete the rear end with a premium motorsport look that perfectly suits the M140i’s stance.
