Quick answer
Wenzel's Automotive in Winthrop Harbor repairs exhaust systems: leaking pipes and joints, mufflers, hangers, and catalytic converter problems. An exhaust leak is more than noise. It can let fumes into the cabin and can cause an emissions failure.
What is included
- Exhaust leak inspection
- Pipe, joint and muffler repair or replacement
- Hanger and heat shield repair
- Catalytic converter and oxygen sensor diagnosis
Signs you need it
- The car is louder than usual
- A rattle from under the car, often a loose heat shield
- An exhaust smell in the cabin
- A check engine light for catalyst efficiency
- Something hanging low under the car
Salt and exhaust systems
Exhaust parts sit low and stay wet, so road salt works on them all winter. Hangers and clamps often rust through first. Catching a broken hanger early can save the pipe it was holding.
Converter codes
A catalytic converter code is not always a bad converter. Misfires, oxygen sensors and exhaust leaks can set the same code. We test before replacing an expensive part.
