Product Details

At Active Autowerke, it’s not ONLY about making as much power as possible. For over 30 years, power has been the end result of improved performance due to our relentless desire to develop a refined, quality product. This philosophy behind our performance parts is best represented by one of the newest additions to our F80 BMW M3 and F82 BMW M4 collection. 

The Active Autowerke F8X rear exhaust was carefully engineered to eliminate the unflattering sound of the factory M3 and M4 exhaust, while also allowing for optimum flow and resonance. Every effort was made in addressing the not so appeasing sound of the stock OEM exhaust, but in designing an exhaust worthy for an "M" car. We believe our rear exhaust combined with our mid-pipe offers the deepest sound and best performance of any other system on the market today.  Available for both models, this axle-back exhaust gives your BMW the deep, throaty, growl a car of its caliber should have had from the factory! And NOW, after many requests from our dedicated customers, we are introducing a valved version of the ultimate exhaust which has been dubbed "Max Max" by our team. We will update dyno charts later but this exhaust flows even better with its valved system.
