BMW 440i F32 F36 LCI Sports Catback Exhaust by Remus

Unlock the soundtrack your 4 Series deserves with this premium flap‑controlled catback from Remus. Crafted from high grade stainless steel and shot blasted for durability, this resonated rear system delivers a deeper, richer tone under load while remaining refined on the cruise. With reduced back pressure for sharper throttle response and a noticeable weight saving, it is the ideal exhaust upgrade for B58‑powered 440i Coupé and Gran Coupé models.

The integrated valve works with the factory electronics, so you keep full OEM flap control from the cabin. Handmade in Austria and EEC approved, this twin outlet left and right system with 84 mm tips blends motorsport character with everyday usability and top tier build quality.
