DCE BMW F97 X3M & F98 X4M High Flow Single Midpipe OPF Delete RDE II (EU Spec)

The DCE High Flow Single Midpipe OPF Delete for the BMW F97 X3M and F98 X4M is designed to reduce exhaust restriction and improve overall exhaust efficiency on EU-spec OPF-equipped vehicles. Manufactured from high-quality stainless steel, this midpipe replaces the restrictive factory OPF section with a smoother, less restrictive design that supports improved throttle response and a more pronounced exhaust tone.

By converting the factory dual section into a single midpipe, exhaust pulses are blended more effectively, resulting in a deeper and fuller sound character. The reduced back pressure also allows the turbochargers to respond more quickly, improving drivability in lower and mid-range engine speeds.
