PART NUMBER: 61-2567
Replacement factory Mazda "donut" style gasket for the junction between header and midpipe on 2006-2015 NC MX5.
If you have a leak at this junction, replacing the gasket might be the fix.
Note this will not stop condensation weep at this joint. It's a moving joint, metal on one side, condensation passing through that sort of flex joint is going to happen and we see it on these cars brand new from the dealership. But if you feel 'puff puff puff' actual exhaust gases leaking then consider a replacement. This is a GENUINE MAZDA factory part, not a cheap copy, we import these direct from Mazda Japan. This is a wear item, they will not last forever, mere soft graphite pressed into the metal mesh and the graphite slowly wears away as the joint moves.
