For the owner of the new G90 M5, the Active Autowerke Signature Catback System offers the perfect balance of luxury refinement and aggressive performance. Constructed entirely from corrosion-resistant T304 stainless steel, this system is built to withstand extreme thermal loads while maintaining a lifetime of consistent finish. The engineering team focused heavily on "Sound Engineering," ensuring that while the exhaust is louder and deeper than stock, it remains completely free of interior cabin drone—a critical requirement for the high-end M5 experience. With its direct-fit installation and a variety of 112mm quad tip finishes, this exhaust provides a surgical fit and a premium upgrade that complements the caliber of the world’s most powerful M-sedan.
