2024+ BMW M340i/M440i Downpipe | G20/G22/G23/G26

*Please email us any special requests*

To get a proper sound from your B58 on the latest G20 LCI M340i and M440i, this performance downpipe is one of the most effective bolt-ons you can make. It’s built specifically for the 2024+ B58 3.0L turbo straight-six, and targets the most restrictive point in the factory exhaust - right off the turbo - to open it up for serious flow gains.

This downpipe helps your G20, G22, G23 or G26 reduce its backpressure which helps get a sharper throttle response, stronger performance through the mid-rev range, and some extra horsepower and torque when paired with a tune. 

It also lets the straight-six turbo breathe more efficiently, which brings out that deep, more aggressive tone that the factory set up wont. 

This piece is constructed from T304 stainless steel with smooth mandrel bends to handle the heat and hold up for the long haul.
