SKU: S-BM/T/38 / UPC: 3831126445027

Akrapovic Evolution Line Titanium Catback Exhaust for 2025 BMW M5 (G90, G99)

The Akrapovic Evolution Line Titanium Catback Exhaust System, designed specifically for the 2025 BMW M5. This full catback setup bolts directly to the factory catalytic converters, delivering dyno-proven gains that sharpen acceleration and refine the driving dynamics of your high-performance sedan or touring model. Crafted from premium titanium, it sheds significant weight compared to the stock system, improving handling and efficiency without compromising durability. The result is a deeper, more resonant tone that evolves with drive modes, filling the cabin with acoustic reflectors and precise tuning for an immersive sound profile that stands out on the road or track.

Key Performance Gains

• Power Increase: +11.5 hp (8.5 kW) at 6,150 rpm
• Torque Boost: +15.6 Nm at 2,550 rpm
• Weight Reduction: -15.5 kg (-34.2 lbs), representing a 41.1% savings over the OEM exhaust for better balance and responsiveness
• Backpressure Reduction: Optimized flow through cast titanium collectors and an X-connection that mixes exhaust gases evenly for smoother delivery across the RPM range

These figures come from Akrapovic's in-house dyno testing against a stock-equipped 2025 BMW M5, ensuring real-world improvements in throttle response and top-end pull that elevate every drive.
