Note: While the Active Autowerke Full Exhaust System is recommended for off-road or racing applications, the Mad Max Rear Exhaust Section is designed to meet the demands of enthusiasts looking to elevate their driving experience.
Refinement Meets Performance: The OEM F8X exhaust utilizes middle and rear silencers as well as exhaust valves to create a sound that aligns with the M3 and M4's reputation. However, after thorough analysis, we realized that a more streamlined approach would enhance the F8X exhaust's performance.
We started by completely redesigning the mid-pipes, significantly increasing exhaust flow and eliminating the uneven sound produced by the turbochargers. The result is a single pipe that not only cancels out unwanted noise but also ensures unrestricted exhaust flow, optimizing performance.
One of the most noticeable differences between the Active Autowerke F8X Rear Exhaust Section and the factory exhaust is our innovative use of dual mufflers. This design creates a vast resonance chamber that effectively eliminates the unpleasant "weed eater" noise often associated with the stock system.
Moreover, our design allows exhaust gases to crossover freely, eliminating back pressure without compromising the deep, aggressive rumble characteristic of turbocharged cars.
Rest assured, each Active Autowerke F8X Rear Exhaust Section undergoes rigorous testing on our in-house F8X Exhaust Fixture to guarantee a precise fit. Elevate your driving experience today with Active Autowerke and unleash the true potential of your F8X BMW M3 or M4.
