If your car's fuel consumption suddenly increases and the power drops, or the check engine light is on, it may indicate that there is a problem with your catalytic converter. If you do not clean the catalytic converter for a long time, it will cause blockage, which will cause irreversible damage to your catalytic converter and engine. If you're viewing this item, chances are you're like the countless other people we run into who have a cracked, leaking, or otherwise bad catalytic converter on their vehicle. Simply unbolt and remove your bad converter and attached piping, and reinstall the new converter and attached piping. You'll be back on the road running as good as new in no time.
