BMW F30 320i LWB Twin Exit Performance Exhaust with Titanium GT90 Tips, Part No. SSXBM1069

Give your 3 Series the soundtrack and presence it deserves. This Milltek Sport catback system for the BMW F30 320i L Model Long Wheel Base, including LCI facelift years 2012 to 2020, delivers a straight-through, non-resonated layout with a twin exit conversion and stunning 90 mm titanium tailpipes. Expect sharper throttle response, freer flowing pipework and a purposeful motorsport tone that sets your 320i apart on road and track.

Built in the UK from premium T304 stainless steel, the system uses precision mandrel bends to maintain consistent pipe radius for optimised gas flow. Acoustic tuning focuses on a crisp, sporty note with minimal cabin boom. The dual outlet layout requires the BMW M340i rear valance to complete the conversion and achieve the OEM plus finish enthusiasts want.
