Responding to the fervent requests of our valued customers, Active Autowerke proudly unveils the Signature Single Mid-Pipe tailored for the BMW X3M and X4M. Leveraging our expertise with the single mid-pipe design from the revered F8X and G8X M cars, we bring an enhanced experience to the X3M and X4M SUVs. Brace yourself for a more commanding and resonant tone that transforms the stock exhaust into something extraordinary.

While these SUVs have garnered accolades for their performance, the sound has been somewhat subdued, leaving drivers wondering if they are truly behind the wheel of a BMW M vehicle. To address this, Active Autowerke has crafted a comprehensive exhaust system for the X3M/X4M, comprising a mid-pipe, a rear axle-back valved exhaust, and a set of GESI catted downpipes. This overhaul of the stock exhaust unleashes an astonishing soundscape, enveloping you in the true essence of an M-car driving experience.

This exhaust system upgrade has been meticulously designed and engineered to seamlessly integrate with most aftermarket exhaust systems and mufflers available today. With just a single cut required in the stock mid-pipe, installation is a breeze and accessible to most enthusiasts. Furthermore, should the need arise, the stock mid-pipe can be easily reinstated.

Rest assured, this system maximizes flow, reinstating the signature growl anticipated from any BMW M-Series car. Active Autowerke has perfected the art of blending the sounds earlier and for an extended duration, resulting in a deeper and more resounding exhaust note.

The Active Autowerke single mid-pipe system is meticulously crafted from premium 304 brushed stainless steel, ensuring longevity and durability. We stand behind the quality of our product with an industry-standard warranty against rust.

As the newest addition to our esteemed signature lineup, this offering is a must-have for the discerning enthusiast seeking a more sonorous car that truly complements its awe-inspiring performance.
