Active Autowerke Swain Coated Catless Downpipe For Bmw M3, M4 2014-2019

Description:

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. 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!
