2ZR HJS HD Catalyser to OEM manifold
There are two catalyser installs on the Toyota-engined Elises which destroy their factory catalysers more than the other motors. One is the 2ZZ Elise SC model. The other is this one - the 2ZR motor!
This manifold has a different 2-bolt flange to the factory manifold fitting than the 2ZZ and a different bore downpipe to the catalyser. This downpipe is 60mm diameter. Any larger and you're damaging torque. Use any other catalyser apart from the 130mm diameter HJS HD catalyser and you will have a CEL.
Only 2bular designs and builds an HJS HD catalyser to fit to the factory manifold.
The gasket cup is TIG-welded to the flange. A unique 2bular feature. Forget about loose flanges and bigger bore downpipe - only 2bular pay attention to these parts.
