Exhaust Seal Ring, Manifold to Section 1, BMW - E46 M3, E9X M3, MZ3, Z4M

This metal seal is used to seal each pipe from the exhaust manifold or header to the front section 1 on E46 M3, E9X M3, and E85/E86 Z4M. The seals deform when the pipes are fully tightened down which makes them almost impossible to re-use. This is a Genuine BMW front exhaust seal with a two year warranty. Sold per gasket seal.
