Introducing the revolutionary Active Autowerke Signature Equal Length Mid-Pipe, an unparalleled upgrade tailored exclusively for the BMW G80 M3 and G82 M4. As trailblazers in developing the first-ever equal-length mid-pipe for the F8X M cars, we now bring our expertise to the G8X M cars, offering a remarkable alternative to our renowned X-Pipe and Single Mid-Pipe for the G8X. Prepare to embark on a transcendent journey of sound and performance with our cutting-edge equal-length exhaust system.

While these exceptional vehicles have garnered widespread acclaim for their remarkable performance, the stock exhaust often leaves drivers yearning for the unmistakable sound that embodies a true BMW M-car. Addressing this longing, Active Autowerke has meticulously engineered a comprehensive exhaust system for the G80/G82, featuring a selection of three mid-pipes, including this groundbreaking equal-length option, a rear axle-back valved exhaust, and a set of GESI catted downpipes. This transformative upgrade breathes new life into your G80/G82, endowing it with an awe-inspiring sound that rekindles the sheer joy of driving.

Our equal-length mid-pipe is the pinnacle of design and engineering, finely tuned to rectify the passenger side exhaust length and achieve true equal length, resulting in a smoother and more harmonious sound profile. This groundbreaking technology has earned us recognition, evident through our US Patent 11248511, approved in the UK and EU.

Designed for seamless integration with most aftermarket exhaust systems and mufflers available today, this upgrade requires only two cuts in the stock mid-pipe. Its straightforward bolt-on installation can be easily undertaken by most enthusiasts, with the added flexibility of reverting to the stock mid-pipe if desired.

Crafted from premium 304 brushed stainless steel, the Active Autowerke equal-length mid-pipe ensures maximum flow and uncompromising durability. Rest assured with our industry-standard warranty against rust, guaranteeing a lasting and gratifying ownership experience.
