Scorpion Cat-Back Exhaust System - BMW M3 (F80) / M4 (F82/F83) - 70mm
This Scorpion cat-back exhaust replaces the factory system on the BMW M3 Sedan (F80) and M4 Coupe and Convertible (F82/F83). It is made from T304 stainless steel with twin 70mm (2.75") pipework, keeps the electronic valves and finishes in quad 90mm tailpipes. This is a non-resonated system, so expect a noticeably louder and more aggressive sound than the factory exhaust. Scorpion lists it for GPF and non-GPF cars, fitting the factory system or Scorpion front sections.
Options – Tailpipe finish: Daytona Polished Stainless – Scorpion's round Daytona tailpipes in a polished stainless finish; Daytona Black Ceramic – the same Daytona tailpipes with a black ceramic coating; Ascari Carbon Fibre – tailpipes with a carbon fibre outer sleeve.
Note: The factory system must be cut to fit this cat-back unless it is fitted with Scorpion's SBMC073 or SBMX073 front section. No Australian-delivered BMW has a GPF. Installation by a professional is recommended.
