With RepairPal&rsquo;s national average at $2,280 to $2,480 installed, a converter can be a large share of an older car&rsquo;s value. If the engine is healthy and the car passes inspection otherwise, replacement usually makes sense, since removing the converter is illegal and states with emissions inspections will fail the car without one.<\/p> <\/div> <div class=\"schema-faq-section\" id=\"faq-question-1793900659822\"><strong class=\"schema-faq-question\">Can I drive with a bad catalytic converter?<\/strong> <p class=\"schema-faq-answer\">Short trips are usually possible, but it is not a good idea to wait. A clogged converter can cause power loss and overheating, and a failed one will keep the check engine light on and fail an emissions inspection.<\/p> <\/div> <div class=\"schema-faq-section\" id=\"faq-question-1793900659823\"><strong class=\"schema-faq-question\">How long does catalytic converter replacement take?<\/strong> <p class=\"schema-faq-answer\">It depends on the design. A bolt-on, direct-fit converter is a much shorter job than a welded or manifold-integrated one.

With RepairPal's national average at $2,280 to $2,480 installed, a converter can be a large share of an older car's value.
