Akrapovič Slip-On Line (Titanium) Exhaust System

This high-quality and lightweight titanium exhaust system is finished with handmade carbon fiber tailpipes. The system is 35% lighter than the original exhaust and utilizes cast collectors produced in Akrapovič’s own foundry.

The Slip-On Line (Titanium) comes with an Akrapovič control kit specifically developed for this system, ensuring a perfect sound experience. The exhaust sound is rich and pleasant during normal driving, but transforms into a deep sporty tone when the driving style becomes more dynamic. The soundscape remains balanced at all RPMs, combining comfort and sportiness into one package.

The tailpipes feature a striking octagonal shape, made from lightweight titanium and finished with a carbon fiber outer shell. For those who prefer a more traditional look, a classic round model is also available.

Performance

• Power Increase: +8.0 kW (10.9 hp) @ 6,000 rpm

• Torque Increase: +13.9 Nm @ 5,000 rpm

• Weight Saving: -8.3 kg

In tests conducted on Akrapovič's dynamometer, the exhaust system produced an 8.0 kW (10.9 hp) power increase at 6,000 rpm and an additional 13.9 Nm of torque at 5,000 rpm, compared to the BMW M4 Competition with the original exhaust system. No reprogramming of the engine control unit is required. The system is suitable for vehicles with and without an OPF filter, but ECE approval only applies to models equipped with an OPF filter.

Optional Accessories

For closed-course use, separate Link Pipes and downpipes are available. Additionally, the Akrapovič Sound Kit is available, allowing the driver to control the exhaust soundscape with even greater precision.

Please note that installing optional link pipes, downpipes, or the Akrapovič Sound Kit invalidates the ECE type approval of the Slip-On Line (Titanium) system.

The appearance can be further enhanced with a separately available handmade carbon fiber rear diffuser, which highlights the striking Akrapovič tailpipes.

Compatibility

The exhaust system is also suitable for the following models:

• BMW M3 xDrive

• BMW M3 Touring (G81)

• BMW M4 Competition (G82/G83)

• BMW M4 Cabriolet (G83)

• BMW M4 CSL

Please note that ECE type approval does not apply to the CSL model.

The Slip-On Line (Titanium) exhaust system is ECE approved for vehicles equipped with a Gasoline Particulate Filter (GPF/OPF).

Mandatory additional part: The Carbon Fiber Tail Pipe Set must be ordered separately. Models TP-CT/69, TP-CT/68, or TP-CT/73/CF are available.
