True performance, durability, and attractive weight advantages with innovative features places the Active Autowerke E9X BMW M3 exhaust in a class of its own. This system is constructed from 100% 304-stainless steel and features adjustable Active Autowerke double walled tips, making it ideal both for 2-door and 4-door models (also allows for cleaner fitment with diffusers).

This system uses factory style flanges making it a complete bolt on system that requires no cutting or welding. The system is a straight-through design providing substantial improvements to gas flow over the factory exhaust.

The sound is unobtrusive, with a rich mellow tone and delivers a solid 5+hp, with key gains in the mid-range. In addition, the Active Autowerke E9X M3 Signature Exhaust system features large 3" piping for maximum exhaust flow while maintaining enough back-pressure to result in horsepower increases across the entire RPM range.

The factory E9X M3 muffler features a Noise Canceling Chamber inside the muffler and Active Autowerke has retained this feature by adding two custom Active Autowerke noise canceling chambers (NCC)on each muffler to reduce/minimize the drone (the 'booming' noise some muffler emit at cruising speeds, ~3500 rpm).

The Active Autowerke E9X M3 Signature Exhaust System provides increase in horsepower, great sound and appearance making it a must for the true M3 enthusiasts.

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 their Signature M2 Competition 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, they have created a modular exhaust system that will provide enough flow to support power levels way above the stock M2 Competition. When installed as a complete unit, the exhaust diameter of our system never shrinks below 3.5” The rear section splits from a single 3.5” pipe in to dual 3.5” pipes; one of which is valved and leads straight to the exhaust tips with the other leading to a straight through muffler that reduces noise levels when the valve is closed. The Y-pipe is hand built to maintain maximum exhaust velocity throughout the entire system. With the reduced back pressure and large single-pipe design you can expect exhaust velocity to remain as high as possible throughout the entire system. The design is also capable of handling much higher power levels than stock. It’s over engineered to have no issues handling the increased exhaust volume from extensive modifications including turbo upgrades. The stock M2 Competition sounds great, but there’s always room for improvement! They configured 7 different muffler and resonator setups before settling on the final product. With the valve closed the system is slightly louder than stock but with a great note. With the valve open it’s significantly louder but without the metallic, hollow sound of a full straight pipe exhaust. MADE IN THE USA FEATURES: Mandrel bent 304-stainless construction Completely TIG Welded (No MIG Welding at all) Flow efficient Y-Pipe design Perfect fitment with adjustable 90mm double walled tips True 3.5” turbo back design Uses OEM valve motor Designed to be used at stock power levels along with highly modified engines No permanent modifications required Manufactured in house in Miami, FL.

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.
