Introducing the exceptional Signature Race Only catback exhaust system by Active Autowerke, specially crafted for the BMW G80 M3 and G82 M4. Building upon our extensive expertise in single mid-pipe design and years of fine-tuning performance for BMW M-cars, this exhaust system is a testament to our commitment to delivering unrivaled power and sound. Prepare for a deeper, more resonant tone that transforms the stock exhaust into a symphony of performance.

While these extraordinary cars have garnered widespread acclaim for their remarkable performance, the sound has been somewhat subdued, leaving drivers yearning for a true BMW M-car experience. Active Autowerke has developed a full race-only exhaust system for the G80/G82, delivering the raw and thunderous sound that discerning BMW enthusiasts crave. Please note that this exhaust system is intended for race track use only, as it produces a loud sound when the exhaust is fully open at all times and does not utilize OEM valves. For those seeking maximum auditory impact, we've also introduced the option of an exhaust DUMP, positioned right after the downpipes, to unleash an awe-inspiring sound.

This exhaust system upgrade has been meticulously designed and engineered to replace the entire exhaust system without the need for any cuts in the stock components. With its straightforward bolt-on installation, most enthusiasts can easily perform the upgrade, and if desired, the stock exhaust can be effortlessly reinstated.

Rest assured, this system maximizes exhaust flow, delivering a race car growl that is both thrilling and invigorating—a sound seldom realized from a BMW M-Series car. The thoughtfully integrated resonators help minimize rasp from the S58 engine, striking a perfect balance between an aggressive, wide-open sound and refined acoustics.

Crafted from premium 304 brushed stainless steel, the Active Autowerke race-only exhaust system guarantees exceptional durability and longevity. We back the quality of our product with an industry-standard warranty against rust, ensuring your investment is protected.

As the newest addition to our esteemed Signature lineup, this offering is a must-have for true enthusiasts seeking an immersive and dynamic driving experience where the exhilarating sound matches the extraordinary performance.
