Diagram ref no 7

Located between the manifold / heat exchanger and the catalytic converter / exhaust pipe connection on Porsche models using the M96 / M97 / M98 engines.

Original gaskets may deteriorate over time due to heat, corrosion, and mechanical stress, allowing exhaust gases to escape. Leaks at this junction can cause noise, performance loss, and potential exposure of heat to nearby parts. An OE-Match version restores correct sealing, prevents leaks, and helps preserve the intended exhaust behaviour.
