Genuine BMW 18307851168 M2 Competition, M3, M4, S55 F87 F80 F82 F83 Downpipe to Midpipe Exhaust Gasket
This is one part which must be replaced every time the exhaust is separated from the downpipes on the S55 in your M2 Competition, M3 or M4 (F80, F82, F83, F87) to avoid annoying exhaust leaks spoiling the show.
The soft material of these gaskets allows them to conform to the components as the exhaust is mated to the downpipes. This means they rarely seal perfectly even if the same components are being refitted. If you're replacing the downpipes then the gaskets will likely crack or splinter during removal.
Sold and packaged individually - each engine requires two.
