Frequently Asked Questions

Does the Akrapovic DI-BM/CA/11/G fit both the BMW M5 G90 sedan and the M5 Touring G99?

Yes. The DI-BM/CA/11/G is engineered to fit both the 2024+ BMW M5 (G90) sedan and the M5 Touring (G99). Always confirm chassis codes match your specific vehicle before ordering.

Can I install the DI-BM/CA/11/G on my M5 if it has the factory trailer tow hitch?

No. Akrapovic specifies that the DI-BM/CA/11/G cannot be installed on vehicles equipped with a genuine factory trailer tow hitch. If your vehicle has this option, the diffuser will not fit correctly.

What is the weight of the Akrapovic DI-BM/CA/11/G versus the factory diffuser?

The DI-BM/CA/11/G weighs 1.23 kg (2.7 lb), compared to the factory unit at 1.86 kg (4.1 lb). This is a weight savings of 0.6 kg, representing a 33.9% reduction in diffuser weight.

Is the Akrapovic DI-BM/CA/11/G road legal?

Yes. The DI-BM/CA/11/G carries ABE approval for European road use. In the United States, this is a styling component and does not affect emissions compliance.

Does the DI-BM/CA/11/G work with the Akrapovic exhaust system for the BMW M5 G90?

The DI-BM/CA/11/G is specifically designed to highlight and complement the Akrapovic Tail Pipe Set (Carbon) for the BMW M5 G90/G99. While it can be installed independently, the visual effect is optimized when used with the Akrapovic Tail Pipe Set.

How long does installation of the DI-BM/CA/11/G take?

Akrapovic rates installation at approximately 150 minutes. The diffuser mounts directly to the factory attachment points without any cutting, drilling, or permanent modifications to the vehicle.

What does High Gloss mean for the Akrapovic carbon fiber finish?

The high gloss clear coat applied over the carbon fiber weave produces a deep, mirror-like shine that shows off the carbon pattern prominently. This is a show-quality finish suited for clean builds where visual impact at the rear is a priority.

How is the Akrapovic DI-BM/CA/11/G manufactured?

The DI-BM/CA/11/G is hand-made in-house at Akrapovic’s production facility in Slovenia. Each unit is individually crafted using premium lightweight carbon fiber, with quality inspected at every stage of production before leaving the factory.

Is this a completely new design or a carryover from a previous M5 generation?

This is a completely new design created specifically for the G90 and G99 generation BMW M5. It does not share geometry with diffusers for earlier M5 generations (F90, E60, etc.).

Does the Akrapovic carbon diffuser come with a warranty?

Akrapovic carbon fiber accessories are covered under the manufacturer’s limited warranty. Contact Black Ops Auto Works for full warranty details and claim support for your region.
