Introducing the highly anticipated Signature Mid-Pipe with X-Pipe by Active Autowerke, designed exclusively for the BMW G80 M3 and G82 M4. While these exceptional cars have garnered widespread acclaim for their performance, the sound has left drivers yearning for the unmistakable roar of a BMW M-car. In response, Active Autowerke has developed a comprehensive exhaust system for the G80/G82, consisting of this remarkable mid-pipe, a rear axle-back valved exhaust, and a set of GESI catted downpipes. Together, these enhancements breathe new life into the stock exhaust, resulting in an awe-inspiring sound that redefines the driving experience. Prepare to feel the true essence of an M-car coursing through your veins once again. We offer systems with or without secondary cats to cater to your specific driving preferences. The catted version offers a slight reduction in exhaust volume while providing a deeper, more resonant tone.

This exhaust system upgrade has been meticulously engineered to seamlessly integrate with most aftermarket exhaust systems/mufflers available today, requiring only a single cut in the stock mid-pipe. It's a bolt-on solution that can be easily performed by most enthusiasts, and should the need arise; the stock mid-pipe can be effortlessly reinstalled.

Rest assured, this system provides unparalleled flow, effectively restoring the signature sports car growl that is synonymous with BMW M-Series cars. For those seeking additional enhancements, we offer an optional upgrade to replace the restrictive secondary cats with high-flow 100-cell flat cats, resulting in a slightly deeper exhaust note. Additionally, stay tuned for an upcoming resonator upgrade, perfect for enthusiasts who prefer a smoother sound profile for their exhaust systems.

Active Autowerke's expertise shines through in the enhanced design of the mid-pipe, optimizing flow and eliminating the two sets of resonators. The X-Pipe configuration further enhances performance by creating a scavenging effect, yielding modest horsepower gains.

Crafted from premium 304 brushed stainless steel, the Active Autowerke X-Pipe system guarantees exceptional durability and longevity. We stand behind 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 an absolute must-have for true enthusiasts in search of a more exhilarating sound to match the breathtaking performance of their BMW.
