For the F22 and F23 M240i (B58, no GPF) - this is the Remus non-resonated valved cat-back. Not a 'quiet mode' compromise. Not a resonated OEM-plus loop. Just full-throttle flow, sharp throttle response, and a proper B58 bark when open.

• Fits only F22/F23 M240i with B58 engine and no GPF - not for G20, G22 or post-2021 facelifts
• Valve control via OEM switch - no coding, no extra wiring, no guesswork
• Non-resonated mid-section - zero drone at cruise, zero restriction under load
• 102mm angled carbon tips with titanium internals - bolt-on, no trimming, no alignment drama
• Stainless steel throughout - 304 grade main pipes, T304 flanges, laser-cut brackets
