Engineered to elevate both performance and design, this Armytrix catback exhaust system for the BMW M3 F80 and M4 F8x is crafted from top-grade T304 stainless steel and designed for a flawless fit. It includes active valves (valvetronic) that adapt the exhaust tone at the push of a button, either via remote control or smartphone app. With valves open, it delivers an aggressive, race-inspired soundtrack, while with valves closed, it offers a more discreet yet still sporty tone. The tailpipes—available in chrome, black, carbon fiber, or titanium blue—add a distinctive visual upgrade to the rear end.
Delivered with a complete mounting kit and installation manual, this exhaust system reflects the precision and build quality that makes Armytrix a leader in premium performance upgrades.
