Customer Guides

Are aftermarket catalytic converters legal in all states?

No, they are not. Emission laws differ from state to state, but one place that is said to be the toughest on air emissions is California. Generally, a catalytic converter that is legal in California is legal everywhere else. Cat con manufacturers will usually label whether or not their products are legal in California.

 

Should an aftermarket catalytic converter be installed when upgrading a Honda Odyssey engine?

The Catalytic converter that comes with the Odyssey does a decent enough job of cleaning the minivan's exhaust. If an Odyssey owner is thinking of upgrading their engine for better performance, then the old converter may not probably be up to the job. After going through all the trouble to upgrade his engine, the owner may find his vehicle failing the emission test and being forbidden from leaving the garage. Getting high performance aftermarket catalytic converters are undeniably a good idea in such cases.

 

Why do catalytic converters get stolen and how can it be avoided?

Catalysts contained within the catalytic converter include precious metals like platinum and rhodium. These make cat cons look like a goldmine to many thieves. Catalytic converters are stolen mostly from vehicles with a large clearance beneath them, since a thief could easily crawl underneath such vehicles. It only takes about t 2 minutes to complete the theft, the same amount of time an average person could spend picking up a six pack from the convenience store. Some ways to prevent cat con theft include parking in places with plenty of people around and avoiding dark parking lots. Cages can also be installed to make it hard for any thief to get to the converter.

 

Will catalytic converters ever need to be replaced?

If an Odyssey owner takes extremely good care of the minivan and avoids going off-road, then the cat con will probably last as long as the vehicle itself.

P0430 Code: Catalyst System Efficiency Below Threshold  (Bank 2)
P0430 Code: Catalyst System Efficiency Below Threshold (Bank 2)A failing catalytic converter breaks down less pollutants in the exhaust, resulting in lower oxygen (O2) levels overall.

In turn, the computer activates the check engine light and logs the appropriate OBD-II trouble code for diagnosis by a
