Overview

These Milltek Sport parts fit the 2021-2025 BMW M440i and M440i xDrive coupe (G22) with the 3.0 liter B58 turbo six. This large-bore 4.5 inch Milltek downpipe opens up the B58 turbo six, with a 200-cell race cat or as a catless track pipe. A Milltek hot-side part replaces the restrictive factory section with larger, smoother T304L tubing, so exhaust gas leaves the engine with less resistance. Pick a catted version to keep a catalytic converter in the system, or a catless version for a dedicated track car. The BMW M440i G22 parts are T304L stainless steel with mandrel-bent tubing, which keeps the pipe at full size through each bend and resists corrosion for years. They bolt in place of the factory parts with no cutting or welding.

How to Choose

Choose the Part you need. Catless Downpipe has no catalytic converter. It is for off-road and track use only and needs an ECU remap. Catted 200-Cell Race Cat Downpipe keeps a 200-cell high-flow catalytic converter. Milltek recommends an ECU remap with it.

Pair them with the Milltek cat-back for the BMW M440i G22 for a complete Milltek exhaust.

90 mm (3.54 in) T304L stainless steel pipework
