Akrapovic 2024+ BMW M5 (G90,G99) Evolution Catback Exhaust - Titanium (Requires Tips) - S-BM/T/38

The Akrapovic Evolution Line Catback Exhaust (S-BM/T/38) is a premium, high-grade titanium cat-back exhaust system engineered specifically for the 2024+ BMW M5 (G90 / G99). Crafted from lightweight titanium and featuring Akrapovic's hallmark precision manufacturing, this system delivers measurable power gains, a significant weight reduction over the factory exhaust, and a deep, refined exhaust note — all without requiring an ECU remap. Please note: tailpipes are required but sold separately — see the Fitment and FAQ sections for details.

Key Features & Benefits

• Proven Power Gains: Dyno-tested to deliver +8.5 kW (11.5 hp) at 6,150 rpm and +15.6 Nm of torque at 2,550 rpm compared to a stock BMW M5 exhaust — real, measured results from Akrapovic's in-house dyno.
• Dramatic Weight Reduction: This system is 41.1% lighter (15.44 kg) than the stock exhaust, contributing to improved handling dynamics and a lower overall vehicle weight.
• High-Grade Titanium Construction: The entire system is built from lightweight titanium, including complex components like the X-connection and specially designed collectors, which are cast at Akrapovic's in-house titanium foundry for uncompromising quality and precision.
• Signature Akrapovic Sound: The X-connection allows exhaust gases from both sides of the engine to mix, working alongside acoustic reflectors on the tailpipes and a specially tuned resonator to deliver a deep, sporty tone across all drive modes. An additional damping element in the link pipe further refines sound quality and comfort.
• Increased Main Tube Diameter: The main exhaust tubes feature an increased diameter compared to stock, improving exhaust flow for better performance.
• No Exhaust Valves: The system is designed without exhaust valves, offering a consistent, unfiltered Akrapovic sound experience at all times.
• Plug-and-Play Installation: No ECU remapping is required — the system is designed for a straightforward installation on compatible vehicles.
• Choice of Tailpipe Styles: Buyers must choose between round or hexagonal tailpipes, available in carbon-fibre or titanium finishes, allowing for personalized aesthetics to complement the system.

Frequently Asked Questions

Q: Do I need to buy tailpipes separately?
A: Yes — tailpipes are required to complete this exhaust system and are not included with the S-BM/T/38. Akrapovic offers both round and hexagonal tailpipe styles in carbon-fibre and titanium. You must choose one option to complete the installation. Contact our team for help selecting the right tailpipes for your build.

Q: Does this exhaust fit a BMW M5 with an OPF or GPF?
A: This system has been developed for BMW M5 G90/G99 vehicles without a gasoline particulate filter (OPF/GPF). Akrapovic notes that their performance tests were conducted on an OPF-equipped vehicle, but the system is designed for non-OPF/GPF fitment. If you are unsure whether your vehicle has an OPF or GPF, please contact our fitment specialists before ordering.

Q: Will I need to remap my ECU after installing this exhaust?
A: No. The Akrapovic Evolution catback for the BMW M5 G90/G99 is designed as a plug-and-play installation, meaning no ECU remapping is required. Power and torque gains are achieved without any tuning changes.

Q: How much does this exhaust weigh compared to stock?
A: The Akrapovic Evolution titanium system is 15.44 kg (41.1%) lighter than the stock BMW M5 exhaust — a substantial reduction that benefits overall vehicle dynamics in addition to the performance gains.
