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!

Active Autowerke is proud to announce the release of the Signature F8X M3/M4 Exhaust System. This system is the result of countless hours of R&D to obtain the perfect combination of performance and sound. Constructed of 100% 304 TIG welded stainless steel, Active Autowerke has created a modular exhaust system that will provide enough flow to support power levels way above the stock S55. The stock S55 Midpipe is a dual-pipe system from each turbo that leads to the rear muffler. The resulting sound is far from pleasant, and without any real scavenging effect the turbo lag is fairly pronounced. By converting to a single 3.5" pipe directly after the downpipes, AA's system promotes exhaust scavenging along with higher exhaust velocity to produce a quicker spool, more power, and a much smoother exhaust note.
