This really is a job best performed by a muffler shop.
NO!NO!
Cats cost around $150 for an aftermarket one. Not sure for dealer oem price
It should last the life of the car if you maintain the car as you should. Let the engine start running rich and do nothing to repair this condition and it will destroy the converter. But keep the engine tuned up and running as it should and you will never have to replace the converter. NEVER had a problem with my 1996 HONDA ACCORD engine and CATALYTIC CONVERTER needed to be replaced at 220,000 MILES.
You have 2 options. Either you put your catalytic converter back on or you unplug the check engine light. Thanks for killing the environment.
Retail on these are about $880, but the dealer cost is only about $425

I recommend you have this done by a qualified exhaust system repair shop. Make sure the catalytic converter is defective before you replace it, as they are very expensive.
After the exhaust manifold but before the catalytic converter on the exhaust tube.
IT SHOULD BE UNDERNEATH THE CAR BEFORE THE MUFFLER(ABOUT THE CENTER OF THE CAR) JOSE
The oxygen sensor on a 2004 Honda Accord is found on the exhaust system. They are placed close to the catalytic converter so the sensors can properly read the exhaust flow.
It has two. One on the intake manifold and the other in the catalytic converter.
Your catalytic converter is at the top of your motor at the exhaust manifold take out the 4 14mm screws that connect your converter to your manifold drop down out the bottom of engine and replace another really simple fix
