Introducing the highly anticipated Signature Single Mid-Pipe by Active Autowerke, specially designed for the BMW G80 M3 and G82 M4. Building upon our expertise with single mid-pipes from the renowned F8X M cars, this offering provides an exceptional alternative to our X-Pipe Mid-Pipe for the G8X models. Enhancing the exhaust note with a slightly deeper tone, this option delivers an incredible auditory experience at a similar price point, albeit without the secondary cat option.

While these extraordinary cars have received widespread acclaim for their performance, the stock exhaust sound has left drivers longing for the unmistakable roar of a true BMW M-car. To address this, Active Autowerke has meticulously crafted a comprehensive exhaust system for the G80/G82, which includes a choice of two mid-pipes (the single or our x-pipe), a rear axle-back valved exhaust, and a set of GESI catted downpipes. The result is a remarkable transformation of the stock exhaust, immersing you in a symphony of sound that truly reflects the essence of driving an M-car.

Designed for seamless compatibility with most aftermarket exhaust systems and mufflers available today, this exhaust system upgrade requires only a single cut in the stock mid-pipe. Its straightforward bolt-on installation can be effortlessly performed by most enthusiasts, and should the need arise; the stock mid-pipe can be easily reinstated.

Rest assured, this system ensures optimal flow, effectively restoring the iconic sports car growl that is synonymous with BMW M-Series cars. As a testament to our commitment to innovation, we are currently testing an optional resonator upgrade for those seeking a smoother sound profile for their exhaust systems.

Active Autowerke's ingenuity shines through in the meticulous design of the single mid-pipe, strategically blending the sounds earlier and for a longer duration, resulting in a deeper and more resonant exhaust note.

Crafted from top-of-the-line 304 brushed stainless steel, the Active Autowerke single mid-pipe system guarantees unrivaled durability. We stand behind the quality of our product with an industry-standard warranty against rust, ensuring your investment is protected.

As the latest addition to our esteemed Signature lineup, this offering is a must-have for true enthusiasts in pursuit of an exhilarating sound that perfectly complements the astonishing performance of their BMW.
