The Akrapovic S-BM/T/25 Evolution Line Cat Back (Titanium) with Carbon Tips is the definitive exhaust upgrade for the 2020 to 2024 BMW M8 Competition Gran Coupe (F93). Hand-built in Akrapovic's Slovenia factory using the same materials and processes that supply championship-winning MotoGP and World Superbike race teams, the S-BM/T/25 replaces the factory catback system from the catalytic converters back with a full titanium assembly capped with four oval carbon fiber tips. The result is a documented gain of 11 kW (15 HP) at 5,750 rpm, 22 Nm (16 lb/ft) at 2,500 rpm, and a reduction of 10.5 kg (23.1 lbs) from the rear of the vehicle. Every S-BM/T/25 is sonically tuned to deliver the refined, layered BMW S63 V8 growl that the factory exhaust suppresses, building from a civilized idle into a full-throated, high-rpm wail that announces M8 ownership with authority.
Key Features
- Full Titanium Catback System - The S-BM/T/25 replaces the entire stock system from the cats back with hand-welded aerospace-grade titanium front link pipes, rear link pipes, and muffler assemblies, delivering maximum corrosion resistance and thermal stability for a lifetime of use.
- Carbon Fiber Oval Tips - Four carbon fiber oval tips provide a visually aggressive, track-inspired finish that complements the F93 Gran Coupe's wide-body rear fascia and contrasts cleanly with M8 Competition body colors.
- Dyno-Verified Power Gains - Akrapovic's own independent dyno testing records a maximum power gain of 11 kW (15 HP) at 5,750 rpm and a torque increase of 22 Nm (16 lb/ft) at 2,500 rpm on the 4.4L S63 twin-turbo V8.
- Major Weight Reduction - The S-BM/T/25 system weighs 17.9 kg (39.5 lbs) versus the factory system's 28.4 kg (62.6 lbs), removing 10.5 kg (23.1 lbs) and improving rear weight distribution, brake feel, and suspension response.
- Signature Sound Engineering - Akrapovic's resonator and muffler chambers are acoustically tuned for the BMW S63 engine to produce a layered, complex exhaust note from idle through redline, eliminating the stock system's throttled, flat character.
- Direct Bolt-On Fitment - The S-BM/T/25 uses OEM mounting points with provided hardware and clamps. No chassis modification, cutting, or welding required.
- Prop 65 Compliant Disclosure - Includes all required safety information for California residents.
- Lifetime Warranty - Covered by Akrapovic's lifetime warranty against manufacturing defects.

Frequently Asked Questions
Does the Akrapovic S-BM/T/25 fit the BMW M8 Competition Gran Coupe F93 for all model years 2020 through 2024?Yes. The S-BM/T/25 is designed and validated specifically for the F93 Gran Coupe body style with the 4.4L S63 twin-turbo V8, spanning model years 2020 through 2024.
What is the difference between the S-BM/T/25 and the S-BM/T/23 for the BMW M8?The S-BM/T/25 (MPN S-BM/T/25) is designed for the F93 Gran Coupe four-door body style, while the S-BM/T/23 is designed for the F91 M8 Convertible and F92 M8 Coupe two-door body styles. Both are Evolution Line titanium catback systems with carbon tips but have different chassis geometry.
Does the Akrapovic S-BM/T/25 require ECU tuning after installation?No. The S-BM/T/25 is a direct bolt-on catback system. The factory BMW S63 ECU does not require recalibration for this installation, and no additional tuning is needed to realize the documented power gains.
How much power and torque does the Akrapovic BMW M8 Evolution catback add?Akrapovic's own dyno tests show a gain of 11 kW (15 HP) at 5,750 rpm and 22 Nm (16 lb/ft) of torque at 2,500 rpm on a stock F93 M8 Competition with the 4.4L S63 V8 and no other modifications.
How much weight does the S-BM/T/25 remove from the BMW M8 Gran Coupe?The Akrapovic S-BM/T/25 system weighs 17.9 kg versus the factory catback at 28.4 kg, removing 10.5 kg (23.1 lbs) from the rear of the vehicle, which improves weight distribution and suspension dynamics.
Will the Akrapovic S-BM/T/25 trigger a check engine light on the F93 M8 Competition?No. The S-BM/T/25 is a catback system that retains the factory catalytic converters. All oxygen sensors remain in their OEM positions, so there are no conditions that would generate a CEL on a stock F93 M8 Competition.
Does the S-BM/T/25 work with the BMW M8 Competition's active exhaust valves?The S-BM/T/25 integrates with the BMW M8 Competition's factory exhaust valve system. The factory valve actuation wiring and control modules remain in place, and the Akrapovic muffler design accommodates valve operation for quiet mode and sport mode functionality.
Is the Akrapovic S-BM/T/25 legal for street use?The S-BM/T/25 is designed for street use but is not CARB certified. California residents should verify compliance before purchase. All other states: this is a street-legal exhaust system. Always confirm local sound ordinances before use on public roads.
How long does it take to install the Akrapovic S-BM/T/25 on a BMW M8 F93?A professional technician can complete the installation in approximately two to three hours. The system is a direct bolt-on replacement requiring no chassis modification, though professional installation is recommended to ensure proper torque on clamps and hanger alignment.
What warranty does the Akrapovic S-BM/T/25 carry?The S-BM/T/25 is backed by Akrapovic's lifetime warranty against manufacturing defects, covering all materials and workmanship for the life of the exhaust system.
Installation Instructions
- Allow the vehicle to cool fully before beginning work. The factory catback system retains heat for an extended period after engine shutdown.
- Raise and secure the BMW M8 F93 on a lift or jack stands rated for the vehicle weight, with stable support under all four jack points.
- Disconnect the factory exhaust valve actuator connectors at the muffler assemblies and secure the wiring harness clear of the exhaust area.
- Loosen and remove the factory clamps at the catalytic converter outlets on both sides of the vehicle.
- Unclip all factory muffler hangers from the rubber isolator mounts along both sides and at the rear. Support the factory system before releasing the final hanger to avoid dropping it.
- Lower and remove the factory catback assembly. Inspect rubber isolators for wear and replace any that are cracked or deformed before installing the Akrapovic system.
- Install the Akrapovic titanium front link pipes onto the catalytic converter outlets, aligning the flange faces. Attach supplied clamps hand-tight at this stage.
- Connect the titanium rear link pipes to the front links and route the rear sections into the OEM hanger positions. Clip into rubber isolators on both sides.
- Mount the titanium muffler assemblies to the rear link pipes and connect all rear hanger points. Install carbon fiber tips and tighten tip clamps to specification.
- Reconnect the factory exhaust valve actuator connectors to the Akrapovic muffler valve ports.
- Verify all clamps and hangers are fully engaged and symmetrically aligned across both sides before final torque. Torque all clamps to the specifications in the Akrapovic instruction sheet.
- Lower the vehicle and run the engine through a full heat cycle at idle for 10 to 15 minutes. After cooling, re-inspect all clamp joints and re-torque if any loosening has occurred during the first heat cycle.
