The BMW M5 F90 Performance Catback Exhaust (2017–2021) is engineered to enhance sound character, exhaust flow balance, and driving engagement, while maintaining excellent daily drivability.
Designed to work seamlessly with both stock and performance downpipes, this catback exhaust system delivers a deeper, more aggressive V8 tone, improved exhaust efficiency, and a premium visual finish—without drone or fitment compromises.
Perfect for:
Daily-driven performance builds
Sound-focused upgrades
Pairing with a high-flow downpipe for a complete exhaust system
The factory BMW M5 F90 catback exhaust prioritizes comfort and noise suppression, which limits sound character and emotional feedback from the S63 engine.
Upgrading to a performance catback exhaust system allows you to:
Achieve a deeper, sportier exhaust tone
Improve exhaust flow efficiency after the downpipe
Reduce overall exhaust weight
Enhance throttle response and driving engagement
For M5 F90 owners, the catback exhaust is the most noticeable sound upgrade.
Carefully calculated pipe diameter to balance flow and back pressure
Smooth internal transitions to reduce turbulence
Designed to complement both OEM and high-flow downpipes
Manufactured from high-grade T304 stainless steel
Excellent resistance to heat and corrosion
Suitable for long-term daily use and high-performance driving
Precision TIG welding throughout the system

Reinforced stress points to withstand vibration and thermal expansion
Fully compatible with factory electronic exhaust valves
Retains OEM driving modes (Comfort / Sport / Sport+)
Optional non-valved race version available

Carbon fiber tips
Stainless steel tips
Matte / polished finishes
