The Fabspeed BMW M3 & M4 Valvetronic Exhaust System offers a superb “plug and play” upgrade to the restrictive and quiet OEM exhaust. Adding a significant increase in tone, volume, and power. We use Helical valves imported directly from the U.K. to eliminate any risk of valve failure that plague many other options on the market with low quality exhaust valves.


The Fabspeed Motorsport Valvetronic Exhaust System relieves you of the subtle OEM sound and gives you the volume and tone that’s missing from the factory system. With a slight increase in volume on the throttle and a nice burble at idle, this is the perfect “grand touring” M3/M4 exhaust system. Downshift pops and bangs in sport mode are louder, but not obnoxiously so. This system has no drone at all cruising around town or on the highway.
