For over 30 years, Active Autowerke has been the one to turn to for high quality BMW performance products. Committed to enhancing the performance of BMWs through the highest quality products is what Active Autowerke is all about. The newest addition to our BMW F80 M3 and F82 M4 Collection, these F8X downpipes, is a true testament to our outlook on creating innovative products with performance in mind.
The F8X downpipes are strategically engineered to virtually eliminate the immensely restrictive characteristics of the factory F80 M3 and F82 M4 downpipes – therefore reducing radiant heat and increasing performance.
Our initial prototype design didn’t include the flex joints you see in the images above. Without these flex joints, the prototypes created an annoying vibration from within the cabin. We quickly realized the necessity of including flex joints into the design and went back to the drawing board. The works of art you see above are a culmination of years of experience engineering top-notch BMW exhaust products.
Made from 1.3-1.5mm thick 304 stainless steel, our F80 M3 and F82 M4 downpipes can also be finished with a performance enhancing, ceramic coating from Swain Tech Coatings for an additional charge. Developed for precise fitment on both the F80 BMW M3 and F82 BMW M4, the difference in performance will be noticeable the moment you leave your driveway!
