Fitment Note

The KYOSTAR 3D Z-Pipe Midpipe is intended for compatible BMW M340i and M440i models equipped with the B58 turbocharged inline-six engine.

A midpipe is the center section of an exhaust system, connecting the upstream exhaust components to the downstream rear exhaust assembly.

This product features a distinctive 3D Z-Pipe design. Its shaped exhaust routing differs from a conventional straight-pipe or single-pipe midsection layout.

Replacing the factory center exhaust section may alter the vehicle's exhaust sound and character. Actual exhaust tone and volume depend on the factory or aftermarket downpipe, rear muffler, exhaust valves, and other modifications.

The product image shows a metal midpipe assembly and two additional metal connection components. Their exact purpose and installation requirements are not specified.

Before installation, compare the factory midpipe with the product images and verify the upstream and downstream connection locations, exhaust hanger positions, routing, and available underbody clearance.

The supplied specifications do not establish the exact pipe diameter, metal grade, wall thickness, system weight, sound level, or tested horsepower and torque gains.

No specific numerical performance improvements are claimed without supporting vehicle-specific testing.

Professional installation is recommended. Confirm the connection method and any required fabrication or modifications before purchase.

Product Details

Why Upgrade Your Factory Midpipe?

The factory BMW M340i and M440i exhaust systems are engineered to balance everyday comfort, exhaust sound, emissions requirements, and vehicle refinement.

Replacing the compatible factory center exhaust section with a performance midpipe changes the exhaust routing and may create a different exhaust tone.

The KYOSTAR 3D Z-Pipe Midpipe offers a distinctive center exhaust configuration for BMW B58 enthusiasts looking to personalize their vehicle's exhaust experience.

Actual sound changes and performance characteristics depend on the complete exhaust setup. No specific sound level, horsepower increase, or torque gain is claimed without supporting test data.
