Akrapovic Sport Downpipe with Cat - F87 M2 N55
Higher flow downpipe with sport catalytic converter
If your track car project calls for a catalytic converter this Akrapovic F87 M2 N55 Downpipe with Sport Cat is one of the best we have seen. The factory catalytic converter in the downpipe is a major restriction and could develop problems on the track. This higher-flowing and metallic sport cat for the F87 is an ideal alternative with less restriction while not giving up any power to a full cat-less downpipe.
The Akrapovic N55 downpipes flow better than stock and other designs thanks to CAD engineering, oversized stainless steel piping, and OE-style connectors. These are some of the best fitting F87 downpipes we have seen to date. Reducing backpressure makes the turbo more efficient and longer-lasting while minimizing the potential for fault codes and limp modes when on track. With less backpressure the turbo can spool up faster and be more responsive - more boost is available sooner and with less lag.
Race software from Epic Motorsports is strongly recommended with this cat-less downpipe. Additional power and torque gains are realized with our software over only using the downpipe. The Epic race software will also eliminate fault codes and check engine lights that come from using this downpipe with stock software (helping to pass post-race tech inspection).
Notice of Fault Codes/Check Engine Light - Using any Racing downpipe could result in a check engine light and fault codes, even with sport cats. Although we have heard of cases where no check engine light appeared, these Racing downpipes are not designed to meet emissions testing and regulations. Race software that is specific to your mods is strongly advised to better adapt your car to a racing environment, keep the fault codes from appearing, optimize power gains, and improve general drivability. Our Epic Motorsports Race software is strongly encouraged to meet all of your tuning goals.
