The best way to improve power, throttle response, and the exhaust note on your BMW F8X M2C/M3/M4! 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. All of this translates to more power! Constructed entirely of 304 Stainless Steel, these downpipes are designed to last. Engineered in house at Turner Motorsport, using state of the art technology, to ensure OE like fitment and lasting quality. Sporting tig welded construction, 304 Stainless flanges, in an elegant brushed finish. Upgrade your OE downpipes to the Turner Motorsport High Flow Catted Downpipes, for a noticeable bump in performance and power!
Note that our downpipe features a 200 cell high flow catalytic converter, this may throw a check engine light. We recommend our Turner tune to remedy this.
