Hey guys, where does the circle (JF040) exhaust flange go? Between standard exhaust manifold and cat or in between the cat and middle section of exhaust? Between the cat and exhaust I normally use JE291 (the one that's the shape of the exhaust connectors with the bolt holes) but apparently that's wrong.

Thanks

The JF040 ring gasket goes betweeen the exhaust manifold and the cat. The correct gasket for sealing the cat to the exhaust pipe is a JE934.
