For F06 650i (N63B44) owners chasing fast road presence and a factory-integrated quad-pipe look - not track-day flow or decat aggression. This is the full AC Schnitzer system: four 90mm polished chrome tailpipes, two per side, with etched AC Schnitzer branding.
Exact fit for F06 650i - SE, Sport and M Sport models (requires matching rear skirt or carbon diffuser - sold separately)
Uses AC Schnitzer’s high-flow ‘export’ silencer - same unit as their dual-pipe variant, tuned for N63B44 torque and mid-range character
No catalytic converters removed - retains OEM emissions compliance and daily driver usability
