Active Autowerke G20 M340i/G22 M440i Mid Pipe 2025+

The Active Autowerke mid pipe replaces the factory mid section on the 2025+ BMW G20 M340i and G22/G23/G26 M440i. It comes with Active Autowerke's custom G2X chassis brace, which makes room for the larger pipe.

Paired with the Active Autowerke valved rear exhaust, it completes Active Autowerke's catback for these cars.

What It Does

Replacing the factory mid section opens up the B58 and changes its tone, and the custom brace keeps the underbody stiff while clearing the larger pipe. Active Autowerke designed the mid pipe and rear exhaust to work together.

Materials and Construction

304 stainless steel, test-fitted on Active Autowerke's in-house M340i/M440i exhaust fixture, and guaranteed to fit every G-series M340i and M440i. Installed on its own, the stock exhaust needs a cut; all connecting hardware is included. Installed together with the Active Autowerke rear exhaust, no cutting is needed because the whole stock system drops out.
