In 2019, Active took on the challenge posed by the BMW enthusiast community who insisted that it was physically impossible to develop and equal length midpipe for the F8X M platform (all equal length products were full exhaust systems which used the space after the differential to equalize the length) and after a lot of research, development and testing, Active developed the Active Autowerke Signature Equal Length midpipe which was recognized as innovative when Active was granted patents both in the US and in the EU/UK regions. This patent also extends to midpipes on the G8X M platform. Of course, Active has to spend resources defending their patents from all the copycats who primarily source products from China where there are companies willing to look the other way on copyrights and other legal protections. Active thanks its customers for their support so that it can continue to develop and innovate for everyone's favorite car brand BMW.
