Thermal Reactor?

Thermal Reactor?
"Mazda was able to avoid this cost by enriching the air/fuel mixture and increasing the amount of unburned hydrocarbons in the exhaust to actually support complete combustion in a 'thermal reactor' (an enlarged open chamber in the exhaust manifold) without the need for a catalytic converter, thereby producing a clean exhaust at the cost of some extra fuel consumption."
Is it possible to bypass this thermal reactor and lean the air/fuel mixture to have less unused gas? Just wondering what the results would be

The last rotaries to have them were the '79-'80 1st gen RX-7's. In '81 they switched to a cat and have never looked back. It was more than just an open chamber. It had some crazy baffling inside that was absolutely horrid for airflow. A cat is a free flowing device by comparison.
Be careful about what you choose to believe on Wikipedia. Some of it is good info. Other bits aren't.

Nope you had a plain old cast manifold and a cat. All 1st gens 81 and up were this way. The manifold was nothing more than a box. The thermal reactors were big round cast manifolds with internal baffling.
