Fabspeed's valved cat-back exhaust for the BMW M3 and M4 (G80/G82, 2021+), hand-built in the US from T304L stainless steel with CNC tubing and aerospace-grade Helical valves from the UK. It's a plug-and-play fit that keeps the factory valve control, adding volume and a deeper tone with pops and bangs in Sport mode, without drone at cruise. No CEL, no ECU modification, and it's 3lbs lighter than the factory system. Includes Deluxe Quad-Style Tips in a choice of Polished Stainless Steel, Carbon Fiber, Satin Black or Titanium finishes.
