Why are catalytic converters so expensive?
Catalytic converters are costly because they contain precious metals like platinum, palladium, and rhodium that are expensive and volatile in price. The part itself often makes up most of the total repair cost.
Can I drive with a bad catalytic converter?
You can sometimes drive with a partially failed converter, but a clogged one restricts exhaust flow and can damage the engine. It will also fail emissions testing, so replacement is necessary in most states.
What causes a catalytic converter to fail?
Converters usually fail from engine problems such as misfires, oil or coolant contamination, or a rich fuel mixture that overheats and clogs the catalyst. Fixing the underlying cause is important, or the new converter may fail too.
Should I use an aftermarket or OEM catalytic converter?
OEM converters offer the best fit and longevity but cost more, while aftermarket units are cheaper and can be legal if they meet EPA or CARB standards. In emissions-strict states like California, a CARB-compliant converter is required.
How long do catalytic converters last?
A catalytic converter can last 10 years or over 100,000 miles when the engine runs properly. Poor maintenance, misfires, and contamination are the main reasons they fail early.
