Remus OPF/GPF Bypass Mid Pipe/Midpipe (Resonator Delete Centre/Center Section) - Non-Resonated Straight Pipe for BMW F40 M135i xDrive, F44 M235i xDrive Gran Coupe & MINI F54 JCW Clubman ALL4 | GPF/OPF Delete Track Exhaust Upgrade | Stainless Steel

Remus OPF/GPF Bypass Centre Section for BMW F40 M135i xDrive, F44 M235i xDrive Gran Coupé and MINI F54 JCW Clubman ALL4

Turn up the soundtrack and open up the flow. This de‑resonated OPF/GPF replacement mid pipe from Remus replaces the particulate filter section to deliver a harder, more motorsport‑inspired tone and freer breathing on track. It’s a direct, bolt‑on centre section for:

• BMW 1 Series F40 M135i xDrive (2018+)
• BMW 2 Series F44 M235i xDrive Gran Coupé (2020+)
• MINI F54 LCI JCW Clubman ALL4 (2019+)

Hand‑built in Austria from premium stainless steel and shot‑blasted for durability, this non‑silenced mid‑section swaps the factory particulate filter for a free‑flowing straight‑through design. Expect a deeper idle, crisp upshifts and a more aggressive note under load, while keeping back pressure low for genuine performance potential when combined with suitable software.
