Fi Exhaust Single Front-Mid Pipe + Valvetronic Muffler + Quad Silver Tips (Retains OEM Valve Settings - No Remote) - BMW G80 M3/G82 M4 | M-Performance Version | 3.0TT S58 | 2021-Up from Fi Exhaust is an active valvetronic exhaust system that gives you real-time control over your vehicle's exhaust character, shifting between a refined, quiet mode for urban driving and an open, high-performance sound profile for spirited driving without requiring any permanent commitment to either character. Fi Exhaust has been at the forefront of the valvetronic aftermarket exhaust segment, developing systems for the most popular European performance platforms with a focus on build quality, fitment precision, and acoustic refinement that distinguishes their products from lower-tier active exhaust alternatives.
The valvetronic bypass system uses electronically actuated flap valves positioned in the exhaust flow path to redirect exhaust gases through a bypass circuit, bypassing the main muffler baffling and dramatically changing both the exhaust tone and volume. The transition is essentially instantaneous via the included wireless remote control, and many Fi Exhaust applications also support smartphone app control. The system is engineered for each specific vehicle platform to ensure the quiet mode is genuinely quiet enough for residential areas while the open mode delivers the full, unrestricted character the engine is capable of producing.
