Exhaust leak repair cost depends on where the leak is. RepairPal estimates $417 to $596 for an exhaust manifold gasket replacement, before taxes and fees. A pipe or converter calls for a different quote. Have the leak inspected promptly because exhaust can let carbon monoxide build up inside a vehicle.

Ask what is included if a section needs replacement
A catalytic converter is a separate repair category. Get the part number, labor and related hardware on the quote. If there is corrosion nearby, ask what work is needed now and what work can be quoted separately.

Take a suspected cabin leak seriously
CDC says even a small leak can allow carbon monoxide to build up in a vehicle. Carbon monoxide has no smell. If you suspect exposure or feel ill, get into fresh air and seek emergency help.
Frequently Asked Questions
Does every leak need a catalytic converter?
The quote should identify the actual failed part. A manifold gasket, a pipe and a converter are distinct repairs.
Can I use a published estimate for my exact car?
Use it as a benchmark. Ask for a vehicle-specific diagnosis, parts and labor estimate, including taxes and other charges.
