F8X M2C/M3/M4 Z Tech Valved Catback Exhaust

The complete Tone Z Tech system for F87 M2C / F80 M3 / F82 M4, pairing our Z Tech midpipe with an axleback for a full catback setup. Most S55 catback setups force a trade-off: live with single-midpipe drone, or put up with the typical 2,000 RPM rasp that comes with an equal-length design's higher-pitched scream. Z Tech's equal-length design and Z crossover avoid both: best of both worlds, that high-pitched, aggressive note up top, with the rasp down low cleaned up so the S55 stays smooth around town. Built in stainless steel, a real weight savings over the factory system, in dual-resonated or quad-resonated configurations, with a range of tip finishes to match your build. Every catback build can include our Resonated Axleback for the smoothest daily-driving experience.
