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.

What to send

The VIN, the parts already fitted, and what you are trying to achieve. Aftermarket hardware already on the car changes the answer more often than people expect — an existing downpipe decides which calibration file you can run.

Paste it into the form on the contact page, or message it with a photo of the engine bay. We store nothing after the check.

What you get back

A part number, a lead time and the legality label — usually inside the hour on a weekday. If a part will fit but we would not fit it to your car, we say that too, and why.

If we get it wrong

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.
