Fabspeed BMW M5 G90/99 Valved Cat-Back Exhaust (2024+)

The new BMW G90 M5 and G99 M5 Touring deliver incredible performance from the factory, but the exhaust note leaves enthusiasts wanting more. The Fabspeed Valved Cat-Back Exhaust System transforms BMW's latest super sedan and wagon with a deeper, more aggressive soundtrack while maintaining the refinement expected from a modern M car.

Designed, engineered, and manufactured in-house at Fabspeed Motorsport, this premium exhaust system replaces the restrictive factory rear section with a high-flow valved design that enhances exhaust flow, sharpens throttle response, and unleashes the true character of BMW's twin-turbocharged 4.4L V8. Constructed entirely from mandrel-bent T304L stainless steel, every component is built to withstand extreme temperatures and deliver years of trouble-free performance. Similar premium G90/G99 cat-back systems use free-flowing crossover designs and valved operation to improve exhaust tone, flow, and driver engagement.

With the valves closed, the system provides a refined, civilized tone ideal for daily driving and highway cruising. Open the valves and the M5 comes alive with a deeper, more aggressive exhaust note that finally matches the performance capabilities of BMW's flagship sedan and touring models.

The Fabspeed Valved Cat-Back is engineered as a direct bolt-on replacement, utilizing factory mounting locations for precise fitment and straightforward installation. No cutting, welding, or permanent modifications are required.
