Fi Exhaust Valvetronic Muffler + Dual Black Tips (Retains OEM Valve Settings - No Remote) - BMW i8 | 1.5T B38A15T0 | 2014-Up from Fi Exhaust delivers active valvetronic exhaust control backed by the engineering and build quality that has made Fi Exhaust the leading name in switchable aftermarket exhaust systems for European performance cars. The fundamental appeal of a valvetronic system is the elimination of the trade-off between a quiet daily driver exhaust and a performance exhaust — Fi Exhaust's bypass valve design allows both modes to exist in a single system, controlled on demand. This is particularly valuable for vehicles operated in areas with noise ordinances, early morning departures, or simply in situations where a full-noise performance exhaust would be antisocial.

Fi Exhaust engineers their systems with both acoustic targets in mind simultaneously — the quiet mode must be genuinely quiet (not just slightly less loud) and the open mode must deliver the full, unfiltered exhaust character that reveals the engine's true sound at high RPM. Achieving both extremes in a single system requires careful muffler design around the bypass circuit, and Fi Exhaust's years of application-specific development have refined this balance to a high level. The system is built from quality stainless steel with precise fabrication and proper fitment to OEM mounting locations, making installation clean and the finished installation indistinguishable in appearance from a quality OEM exhaust.
