This is a packet of (2) replacement 1/8 Silicone Exhaust Gaskets from REDS Racing which is required to seal the manifold/engine connection on the REDS R5, R5C, R5T and R5TE engines.
NOTE: This part will not work to seal the manifold to muffler connection. REDS lists a separate part number (REDS GM0001) for the manifold/muffler gasket.
