G30 G31 M Sport Quad-Exit Exhaust, AC Schnitzer 1812330212, OPF & Pre-OPF

For G30 and G31 5 Series M Sport models - whether you’re running N20, B48 or B58 engines, pre-OPF (up to June 2018) or OPF-equipped (July 2018+) - this is the AC Schnitzer valved quad-exit exhaust that actually works as intended.

• Direct-fit for G30/G31 M Sport only - includes rear skirt insert; retains factory tow-bar compatibility
• Valve operation remains fully ECU-controlled - no coding, no remapping, no guesswork
• 90mm tailpipes - available in chrome, black ceramic or carbon fibre; all versions use T304 stainless steel throughout
• Two variants covered - pre-OPF (with sound pipe, richer tone) and OPF-compliant (rear silencer + tailpipe kit)
• Not a ‘stage 1’ or ‘track day’ bolt-on - it’s a fast road or daily driver upgrade with OEM+ refinement and proper acoustic control
