BMW 440i B58 3" Mid Pipe for F32/F33/F36 (2017-2021) - Centre/Center Section Exhaust Upgrade | Resonator/Res Delete | Centre Silencer Delete | OPF/GPF/PPF Delete | Straight Pipe Cat-Back Midpipe for 4 Series Coupe, Convertible & Gran Coupe

Transform the soundtrack of your BMW 440i

Give your B58-powered 4 Series the voice it deserves with this centre section upgrade for the BMW 440i F32 coupe, F33 convertible and F36 Gran Coupe, model years 2017 to 2021. This mid-pipe replaces the factory middle section from the catalytic converter to just ahead of the rear silencer, unlocking a deeper, louder, more characterful tone and amplifying the six-cylinder turbo soundtrack.

What you get

• Large-bore 76.2 mm (3 inch) centre pipe that runs from the cat section to before the back box
• Removes the OE centre silencer on non-OPF cars for a more aggressive note
• On OPF-equipped models it replaces the gasoline/particle filter to free up the flow and volume
• Supplied with the required fittings and gaskets for installation and easy return to stock if desired

Why enthusiasts choose this mid-section

Expect a sharper, sportier tone with more presence during acceleration and a richer idle. Our team has fitted this centre pipe to customer 440i builds and the feedback has been consistently positive on sound quality and driving enjoyment. It is an ideal upgrade if you want a res delete, centre silencer delete, OPF delete pipe or straight centre section without changing the rear box.

Fitment and compatibility

• BMW 440i F32 F33 F36 2017, 2018, 2019, 2020, 2021
• Fits both early non-OPF cars and later OPF/GPF/PPF/OPF-equipped variants
• Direct replacement for the factory centre section between the catalyst and rear silencer

Important notes for OPF/GPF/PPF models

• An ECU calibration is required on particulate filter cars to prevent an engine management light after installation
• Removal of the OPF/GPF/PPF is for motorsport and off road use only
