RIDEX 27G0124 Catalytic Converter Rear Gasket – MX-5 Mk1 NA

Replacement RIDEX exhaust flange gasket for the rear catalytic-converter / exhaust connection on Mazda MX-5 Mk1/NA models.

The gasket seals the exhaust flange joint and prevents hot exhaust gases escaping between the mating surfaces. A sound seal helps maintain correct exhaust-system operation while preventing blowing noises, exhaust fumes and soot deposits around the flange.

MX-5 application: MazSpec lists this gasket for the Mazda MX-5 Mk1/NA and describes it as the catalytic-converter rear gasket. Its detailed catalogue covers NA 1.6 and 1.8 applications, while RIDEX/AUTODOC cross-reference the same component to the applicable Mazda exhaust OE numbers.

Common signs of gasket failure include a blowing or ticking exhaust noise, visible soot around the flange, exhaust fumes underneath the vehicle, increased exhaust volume or leakage identified during inspection.

Start the engine after installation and check carefully for exhaust leakage.
