2019-2023 BMW M340i/M440i Downpipe | G20/G22/G23/G26

*Please email us any special requests*

To get that stronger throttle response from the B58, this downpipe is one of the best bolt-ons mods you can make to your 2019-2023 M340i or M440i. 

It’s built specifically for the B58 3.0L turbo straight six, and opens up the exhaust path straight off the turbo to free up air flow where the factory setup is at its most restrictive.

This catless design helps drop back pressure significantly, which means you get a sharper throttle, stronger mid-range pull, and a noticeable bump in horsepower and torque when paired with a tune.

It’s constructed from T304 stainless steel with smooth mandrel bends, meaning it’s built to handle the heat and hold up long-term. Fitment is a direct bolt-on to the factory exhaust and turbo flanges across all G20, G22, G23, and G26 M340i and M440i models running the B58.
