Upgrade the performance and sound of your BMW M340i or M440i with the Akrapovič Downpipe (Catted). Constructed from premium stainless steel and featuring a high-flow 300 cpsi sport catalytic converter, this performance-focused upgrade is designed to work seamlessly with the Akrapovič Evolution Line (Titanium) Exhaust System. Engineered to improve exhaust flow and reduce restriction, it delivers increased power, enhanced torque, and a more aggressive motorsport-inspired exhaust note while maintaining excellent drivability.
Featuring components cast in the Akrapovič in-house foundry, integrated heat insulation, and a flexible central section, the downpipe ensures exceptional durability, precise fitment, and optimal performance. The result is a deeper, more emotional exhaust sound with strong feedback at higher engine speeds and no unwanted drone.
Note: ECU remapping is required after installation to prevent potential check engine warning lights. This downpipe is intended for racetrack use only and does not meet emission compliance requirements for street or highway use. Compatible with Akrapovič Evolution Line (Titanium) systems for BMW M340i (G20) and BMW M440i (G22) non-OPF/GPF vehicles. Not compatible with vehicles equipped with the B58TU2 engine.
