Yes, along with lower fuel economy, and it is highly illegal.
NO!NO!
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
This really is a job best performed by a muffler shop.
First of all its "catalytic converter" and it is on the engine side of the muffler.
The catalytic converter will be underneath the car in the exhaust system directly after the pipe that connects the header (exhaust manifold (connects engine to the rest of the exhaust)) to the Cat (catalytic converter). there will also be a resonator that is closer to the muffler end of the exhaust. The cat has an O2 sensor in it so you'll know if you get the right one.
No, it is illegal to remove a converter and besides the engine will not run right with the converter removed.
Mounted between the engine and the transmission.
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.
