G80 G81 M3 G82 G83 M4 Valved Rear Exhaust by Active Autowerke is the ultimate upgrade for enhancing the sound and performance of BMW’s latest M3 and M4 models. Designed to address the overly muted tone of the factory exhaust system, this rear axle-back exhaust system transforms your driving experience with a deeper, throatier exhaust note that complements the impressive performance of the S58 engine. Engineered with precision, this exhaust system redefines what an M-car should sound like.
The G80 G81 M3 G82 G83 M4 Valved Rear Exhaust is part of Active Autowerke’s comprehensive exhaust solution, which includes a choice of mid-pipes (equal-length x-pipe or single) and GESI catted downpipes. Together, these components create a full exhaust system that delivers a rich, aggressive tone and maximum performance. Even as a standalone upgrade, this valved rear exhaust enhances the factory sound by reusing the original BMW actuator valves, allowing precise control over tone and resonance for a more engaging and dynamic auditory experience.
Crafted from premium materials and designed for optimal flow, this axle-back exhaust system increases the exhaust volume while maintaining excellent performance characteristics. The deep, sporty growl produced by the G80 G81 M3 G82 G83 M4 Valved Rear Exhaust is exactly what enthusiasts expect from an M-series vehicle—bold, powerful, and unmistakably refined. Its robust construction ensures long-term durability, even under the most demanding driving conditions.
Active Autowerke’s philosophy has always been about more than just power—it’s about enhancing the entire driving experience. With over 40 years of expertise in performance engineering, the G80 G81 M3 G82 G83 M4 Valved Rear Exhaust exemplifies the brand’s commitment to quality and innovation. This exhaust system is carefully designed to address the shortcomings of the stock exhaust, creating a sound and performance combination that truly befits the M badge.
This exhaust system can also be paired with the stock mid-pipes for a more subtle improvement in sound. However, the full potential of the system is realized when combined with Active Autowerke’s mid-pipes and catted downpipes, offering a dramatic improvement in both tone and performance. For those upgrading to a mid-pipe later, note that additional connecting pipes may be required.
Upgrade your BMW with the G80 G81 M3 G82 G83 M4 Valved Rear Exhaust and experience the sound and performance transformation that every M enthusiast desires. This axle-back exhaust system ensures your M3 or M4 delivers the iconic sound and dynamic performance that define BMW’s legendary M-series, giving you a driving experience that is as thrilling as it is refined.

PREPREG is a common term for a reinforcing fabric such carbon which has been pre-impregnated with a resin system. This resin system (typically epoxy) already includes the proper curing agent. As a result, the prepreg is ready to be laid into the mold without the addition of any more resin. In order for the laminate to cure, an autoclave production process is used, a combination of high pressure and heat.
- Maximum strength and performance characterictics. In a hand layup production process, it is difficult to achieve 50% fabric and 50% resin content. Typical hand laminates, even when vacuum bagged, end up with a significant amount of excess resin. Excess resin increases brittleness and reduces overall strength properties. On the other hand, most prepregs contain around 35% resin. This is ideal for maximum cured properties and generally impossible to achieve in normal hand lamination.
- Uniformity and repeatability. The prepreg is of uniform thickness and each part coming out of the mold may theoretically be the same. Vacuum bagging technology may have some errors in processing, but prepreg ensures production consistency.
- Reduce curing time. After the thermal curing cycle, no need to wait for the standard 48 hours can be fully cured.
- Aesthetics. Although prepreg processing still requires mold preparation and demoulding, prepreg processing eliminates air bubbles, makes it easier to obtain a smooth, glossy surface as well as eliminates any seaming lines.
