Are there washers on both sides (link and DP) or do they share the same washers? Aka am I buying 4 or 2? Is there any other hardware that should be replaced other than specifically the washers? Do you by any chance have a part number?

Thanks in advance for any insight.

Here’s what I replaced :

Bmw oem part #
Flange (1) - 18327850430
Double Opening Gasket (1) - 18307848046
Crush Gasket (2) - 18307851168
ISA Screw (2) - 07129905867
Copper Collar Nut (4) - 18307597650

Disclaimer: I replaced this at the same as changing my midpipe for an aftermarket one. That said i’m convinced the noise was coming from the hardware above as they are one time use components and I know the previous owner had them re-used.
