How much does a catalytic converter cost to replace?
Aftermarket runs $400 to $1,200, while OEM converters often cost $1,000 to $2,500, more on hybrids.
Why are catalytic converters so expensive?
They contain platinum, palladium, and rhodium, which are precious metals with high market prices.
Can I use an aftermarket converter?
Often yes, but California and CARB states require approved CARB-compliant converters.
Can I drive without a catalytic converter?
It is illegal on public roads and will fail emissions testing, plus it may trigger a check-engine light.
Is it cheaper to repair than replace?
A converter cannot be repaired once the internals fail; the fix is replacement, though the underlying cause should be addressed.
