BMW 440i B58 2016+ Catless Downpipes

BMW 440i B58 Catless Downpipes — B58 3.0L Single-Turbo Inline-6 | 2016+

YPG Motorsport catless downpipes for the BMW 440i F32/F36 equipped with the B58 3.0L single-turbo inline-6. Removing the factory catalytic converters frees exhaust flow downstream of the turbocharger, delivering faster spool, sharper throttle response, and measurable power gains. The B58 responds exceptionally well to exhaust modifications — expect a deeper, more aggressive straight-six tone with turbo whistle and crackle on overrun.

Direct bolt-on replacement — no cutting, welding, or fabrication required.

Frequently Asked Questions

Which BMW models do these downpipes fit?
These downpipes fit the BMW 440i F32 Coupe and F36 Gran Coupe equipped with the B58 3.0L single-turbo inline-6 engine (2016+ model years).

What is the difference between these and M3/M4 downpipes?
The 440i uses the B58 single-turbo engine, while the M3/M4 uses the S55 twin-turbo. Different turbo configuration means different downpipe geometry — these are specifically engineered for the B58 platform.

Do I need an ECU tune with downpipes?
Highly recommended. Downpipes paired with an ECU calibration produce maximum combined power gains, optimize air-fuel ratios, and eliminate check engine lights from the removed catalytic converter.
