G8X M2/M3/M4 Z Tech Midpipe

Most S58 midpipes force a trade-off: live with single-midpipe drone, or put up with the harsh equal-length rasp. Z Tech pairs an equal-length design with a lightweight, 3D-printed SS316 Z crossover and dual resonators, housed in a high-grade SS304 body that's a significant weight savings over the factory midpipe. Equal length is what gives you that higher-pitched scream in the first place, and the Z crossover and resonators clean up the annoying 2,000 RPM rasp that normally comes with it. With Z Tech, you get the best of both worlds: a high-RPM sound that's unmistakably aggressive and refined, with a low-end sound that's perfect for around-town and highway cruising. Fits G87 M2 / G80 M3 / G82 M4. Pair it with an axleback to complete a full catback system.
