Take the performance of your BMW M340i G20 or BMW M440i G22 to the next level with the genuine Akrapovič Downpipe, engineered to maximize exhaust flow, improve turbocharger efficiency, and deliver an even more engaging driving experience. Developed using premium stainless steel and Akrapovič's motorsport expertise, this high-flow downpipe is designed for enthusiasts seeking maximum performance from the BMW B58 engine.
By significantly reducing exhaust restriction compared to the factory setup, the Akrapovič Downpipe allows the turbocharger to spool faster, improving throttle response and increasing both horsepower and torque potential. The optimized gas flow also creates a sharper, more dynamic exhaust character while maintaining excellent refinement during everyday driving.
The precision-engineered construction produces a deeper and more aggressive exhaust note without excessive cabin drone, making it ideal for spirited road driving and track use alike. Every component is manufactured to Akrapovič's exacting standards, ensuring exceptional durability, corrosion resistance, and OEM-quality fitment.
Designed for seamless integration with the factory exhaust system or compatible Akrapovič exhaust systems, the downpipe provides the perfect foundation for a complete performance exhaust upgrade. ECU remapping is required following installation to ensure proper engine management and maximum performance.
Note: This downpipe is intended for non-OPF (Gasoline Particulate Filter) vehicles only.
