Transform your 6 Series with a quad-exit rear box that looks as good as it sounds

Elevate the rear end of your BMW 6 Series F12 or F13 with this AC Schnitzer quad-exit back box and tailpipe set. It is the quad version of the AC Schnitzer dual sports rear silencer and uses the same rear silencer unit on petrol applications, paired with four 90 mm outlets for a purposeful, motorsport-inspired finish.

• Quad 90 mm outlets, two per side for a balanced, aggressive appearance
• Ceramic black tailpipes with etched AC Schnitzer branding for a premium OEM-plus look
• Based on the AC Schnitzer rear silencer used on export petrol models for a high quality fit and finish

Fitment and compatibility

• BMW 6 Series F12 and F13, 640i petrol
• SE and Sport models require the AC Schnitzer rear skirt
• M Sport models require the AC Schnitzer carbon fibre rear diffuser
• Not compatible with the factory standard rear skirt or bumper insert
• Please select the correct engine option when ordering
