Performance Downpipes for BMW M340i / M440i / X3M40i / X4M40i (B58) – Precision Power, Unleashed

Maximize the performance of your BMW equipped with the B58 engine – including the M340i, M440i (G20/G22), and X3/X4 M40i – with high-flow performance downpipes engineered for power, efficiency, and a truly aggressive exhaust tone. Built for the modern BMW driver who demands more than factory limits, these downpipes are optimized for both street and track use.

Crafted from premium T304 stainless steel and TIG-welded for long-lasting durability, our downpipes reduce backpressure and improve turbocharger efficiency. This means sharper throttle response, reduced turbo lag, and a significant increase in horsepower – all while producing a deep, motorsport-inspired exhaust note that transforms the driving experience.

This product is categorized as a motorsport component.
The catalytic converters differ from OEM specifications and fall outside standard parameters in the engine control system. Engine software optimization is required to prevent fault codes.
