F8X BMW M3 & M4 Gen 2 Equal Length Mid Pipe (US Patent 11248511, UK and EU patent 3882441) Cooling The Active Autowerke M340i/M440i rearAfter extensive research and development, ACTIVE AUTOWERKE has announced GEN 2 of our EL midpipes. We worked with our factories to create specially developed RESONATORS that remove rasp from the exhaust tones with minimal change in the volume of the sound. A side benefit is that this also resulted in a reduction in the "2k buzzing" annoying to some BMW owners. GEN 2 replaces the existing F80 M3 and M4 EL midpipe which is no longer available for sale.
