The DI-BM\/CA\/9\/G is designed for all M3 G80 variants including the Competition and Competition xDrive models from 2021 through 2025. It is a direct bolt-on replacement for the factory rear diffuser and requires no modification to the bumper or chassis.\u003c\/p\u003e\n\n\u003cstrong\u003eWill this diffuser fit the BMW M4 Convertible G83?\u003c\/strong\u003e\n\u003cp\u003eYes. The Akrapovic DI-BM\/CA\/9\/G fits the M4 Convertible G83 in Competition xDrive trim from 2021 through 2026. The diffuser shares the same rear bumper architecture across the G82 Coupe and G83 Convertible body styles.\u003c\/p\u003e\n\n\u003cstrong\u003eIs the AKRDI-BM\/CA\/9\/G street legal?\u003c\/strong\u003e\n\u003cp\u003eYes. This diffuser carries ABE type approval, which is the German federal certification for road-legal aftermarket parts. ABE approval is recognized throughout the European Union, and the part is sold and registered as a legal road-use component in numerous markets. It does not affect any exhaust or emissions certification on the vehicle.\u003c\/p\u003e\n\n\u003cstrong\u003eWhat is the difference between the DI-BM\/CA\/9\/G High Gloss and the DI-BM\/CA\/9\/GB High Gloss Black?\u003c\/strong\u003e\n\u003cp\u003eThe DI-BM\/CA\/9\/G features a natural high gloss carbon weave finish that showcases the traditional look of the carbon fiber. The DI-BM\/CA\/9\/GB is finished in a gloss black tinted clear coat, which darkens the weave for a more subtle, monochromatic appearance. Both share identical construction quality, fitment, and ABE type approval.\u003c\/p\u003e\n\n\u003cstrong\u003eDoes the DI-BM\/CA\/9\/G fit the BMW M3 CS or M4 CSL?\u003c\/strong\u003e\n\u003cp\u003eYes. The DI-BM\/CA\/9\/G is confirmed fitment for the 2023-2025 M3 CS (G80) and the 2023 M4 CSL (G82). Note that the M3 CS and M4 CSL use the same rear bumper architecture as the standard M3 Competition and M4 Competition, making the diffuser a compatible direct replacement.\u003c\/p\u003e\n\n\u003cstrong\u003eDoes this diffuser pair with the Akrapovic exhaust for a full system look?\u003c\/strong\u003e\n\u003cp\u003eYes. Akrapovic designed the DI-BM\/CA\/9\/G to visually complement the Slip-On Line Titanium exhaust system fitted with the octagonal carbon tail pipe set (TP-CT\/69) or the round carbon tail pipe set. Together they create a cohesive, motorsport-inspired rear end presentation that is entirely road-legal with ABE approval.\u003c\/p\u003e\n\n\u003cstrong\u003eHow does the Akrapovic carbon diffuser compare to the OEM M Performance diffuser?\u003c\/strong\u003e\n\u003cp\u003eThe OEM BMW M Performance diffuser is also made of carbon fiber, but the Akrapovic DI-BM\/CA\/9\/G offers a notably lighter weight due to Akrapovic's motorsport-derived layering process and their in-house craftsmanship from their Slovenian facility. The Akrapovic piece also carries ABE type approval independently, meaning it meets the same road-legal standard. Many owners choose the Akrapovic version for its deeper gloss finish and exhaust tail pipe compatibility.\u003c\/p\u003e\n\n\u003cstrong\u003eWhat maintenance does the high gloss carbon finish require?\u003c\/strong\u003e\n\u003cp\u003eThe high gloss UV-resistant clear coat on the DI-BM\/CA\/9\/G is durable under normal road use. Akrapovic recommends periodic hand washing with a pH-neutral car shampoo and the use of a quality carnauba or ceramic spray wax to maintain the gloss finish. Avoid automatic car washes with abrasive brushes, and do not use solvent-based cleaners directly on the carbon surface. Periodic inspection of the mounting hardware is also recommended, particularly after track use.\u003c\/p\u003e\n\n\u003cstrong\u003eCan the AKRDI-BM\/CA\/9\/G be installed without professional help?\u003c\/strong\u003e\n\u003cp\u003eInstallation is within reach for an enthusiast with basic mechanical aptitude. The diffuser bolts directly to existing OEM mounting points, and no cutting, drilling, or adhesive bonding is required. Akrapovic includes all necessary hardware. That said, a professional alignment check after installation ensures the diffuser sits flush and symmetrical with the bumper, which is especially important for a showroom-quality appearance.\u003c\/p\u003e\n\n\u003ch4\u003eInstallation Instructions\u003c\/h4\u003e\n\u003col\u003e\n\u003cli\u003eRaise and safely support the rear of the vehicle on a lift or jack stands with the parking brake engaged.\u003c\/li\u003e\n\u003cli\u003eRemove the OEM rear diffuser by locating and unclipping all factory push-pin retainers along the bottom edge and sides of the bumper.\u003c\/li\u003e\n\u003cli\u003eDisconnect any retaining tabs or clips securing the factory diffuser to the bumper lower section and carefully separate it from the bumper skin.\u003c\/li\u003e\n\u003cli\u003eClean all mounting surfaces to remove any dirt or debris before fitment of the new diffuser.\u003c\/li\u003e\n\u003cli\u003ePosition the Akrapovic DI-BM\/CA\/9\/G carbon diffuser against the rear bumper and align all mounting points with the corresponding OEM locations.\u003c\/li\u003e\n\u003cli\u003eInsert and hand-tighten all supplied fasteners and hardware to ensure the diffuser is correctly seated before final torque.\u003c\/li\u003e\n\u003cli\u003eTorque all fasteners to the specification provided in the Akrapovic installation sheet included with the part.\u003c\/li\u003e\n\u003cli\u003eLower the vehicle and perform a visual inspection from directly behind to confirm equal gap and flush alignment on both sides.\u003c\/li\u003e\n\u003c\/ol\u003e\n\n\u003cp\u003e\u003cstrong\u003eWARNING:\u003c\/strong\u003e This product can expose you to chemicals including lead and phthalates, which are known to the State of California to cause cancer and reproductive harm.
