Support · Fitment

Send us your VIN

Your VIN carries the engine code, gearbox, build date and whether the car left the factory with an OPF. Those four things decide which downpipe, which charge cooler and which calibration file you need.

A 2021 G80 M3 built before 03/2021 takes a different mid-pipe to one built after. We check the split rather than guess it.

Paste the VIN into the form on the contact page, or message it with a photo of the engine bay. Aftermarket parts already fitted are worth mentioning — they change the answer. We store nothing after the check.

Unfitted parts come back inside 30 days with no restocking fee and we cover the return label. If we confirmed a fitment that turned out wrong, we also cover the shop time already booked.
