Active Autowerke F8x BMW M3 & M4 Downpipes (Part No. 11-038)


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.

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!
