The Akrapovic BMW 440i (F32, F33, F36) OPF/GPF Slip-On Line S-BM/T/6H

The Akrapovic BMW 440i (F32, F33, F36) OPF/GPF Slip-On Line S-BM/T/6H is built using lightweight titanium, shedding 4.4 kg (9.7 lbs) from the stock exhaust. This 43.2% weight reduction significantly enhances your car’s agility, improving handling and responsiveness. The system includes two sets of newly designed carbon-fibre tailpipes, which lend a premium, motorsport-inspired finish to the rear profile of your 440i.

ECE-Approved with Aggressive Yet Refined Sound

Designed to meet ECE type approval, this Slip-On exhaust offers everyday usability without sacrificing performance. An ECU-controlled valve adjusts back pressure based on driving conditions. At low RPMs, enjoy a smooth and subtle growl ideal for normal cruising. Press the accelerator harder, and the valve opens to deliver a sporty, almost aggressive tone that emphasizes the 440i’s dynamic character.

Performance Gains Across the Rev Range

Optimized exhaust gas flow leads to improved throttle response, enhanced torque, and noticeable power increases. Testing shows gains of up to +6.6 kW around 6,150 rpm and +7.9 Nm near 2,700 rpm, providing stronger midrange pull and brisker acceleration. With better overall engine efficiency, you can expect a more engaging driving experience whether on winding roads or the open highway.

A unique acoustic reflector is integrated before the tailpipes, letting you manually fine-tune how much exhaust sound enters the cabin. For even more control, the optional Akrapovič Sound Kit (P-HF1179) allows on-demand sound adjustments via a dedicated controller. Cruise quietly when you need subtlety, or intensify the exhaust note for spirited drives at the push of a button.
