Scorpion Half System - BMW M440i (G22) - 70mm
The Scorpion half system for the BMW M440i (G22 Coupe) replaces the factory exhaust from behind the rear diff, with new link pipes, a Scorpion rear silencer and quad tailpipes. It's made from 70mm (2.75") T304 stainless, mandrel-bent pipework and keeps the factory electronic valve, so the drive-mode button still controls how loud it is. Scorpion's system weighs about 16.7kg against 17.5kg for the factory part.
Options: Daytona tailpipes are Scorpion's slash-cut 90mm style, in polished stainless or a matte black ceramic coating. STW tailpipes are a straight-cut 90mm polished design. OE Fitment ends in trim bends that sit behind the factory diffuser trims for a stock look.
Note: Australian-delivered BMW have no GPF, so this is the right version for Australian cars. Scorpion lists it for the G22 Coupe only. The factory system has to be cut in two places at the rear diff unless Scorpion's mid pipe is fitted at the same time. The factory valve actuator moves across to the Scorpion valve. Installation by a professional is recommended.
