Take your BMW G80 M3 or BMW G82 M4 to the next level with the genuine Akrapovič Downpipe, engineered to maximize exhaust flow, improve engine response, and unlock the full potential of your performance exhaust system. Developed using premium stainless steel, this upgrade significantly reduces backpressure while delivering a more aggressive exhaust character.

Available in both catalytic and catless configurations, the Akrapovič Downpipe is designed to integrate seamlessly with the OEM exhaust, Akrapovič Slip-On and Evolution systems, or selected aftermarket exhaust systems. The optimized pipe geometry improves gas flow efficiency, allowing the turbocharged S58 engine to breathe more freely under all driving conditions.

Designed primarily for motorsport and track-focused applications, the downpipe delivers sharper throttle response, faster turbo spool, and a more exhilarating exhaust note without introducing excessive cabin drone. Every component is manufactured to Akrapovič's exacting quality standards for outstanding durability, corrosion resistance, and long-term reliability.

When installed together with compatible Akrapovič exhaust systems, the downpipe creates a complete high-performance exhaust solution that enhances both driving dynamics and acoustic performance. For vehicles equipped with aftermarket downpipes intended for closed-course competition use, ECU remapping is required to ensure proper engine operation and prevent diagnostic warning lights.

Whether your goal is increased performance, a more aggressive soundtrack, or preparing your vehicle for track use, the Akrapovič Downpipe is the perfect foundation for a truly uncompromising BMW M exhaust system.
