The best way to improve power, throttle response, and the exhaust note on your BMW F8X M! Restrictive factory downpipes are known to rob your S55 of its true power. Turner Downpipes are less restrictive than OE downpipes, and feature a lower boost threshold, with improved turbo response. Constructed entirely of 304 Stainless Steel, these downpipes are designed to last. Engineered in house at Turner, using state of the art technology, to ensure OE like fitment and lasting quality. Upgrade your OE downpipes to the Turner High Flow Catted Downpipes, for a noticeable bump in performance.
