Catalytic Converter Replacement at Clutchland

The catalytic converter reduces harmful exhaust emissions by converting carbon monoxide, hydrocarbons, and nitrogen oxides into less harmful gases. When it fails, you may notice a rotten egg smell, reduced engine performance, a rattling noise from underneath, or a check engine light with efficiency codes. At Clutch Automotive, we diagnose converter failures by comparing upstream and downstream oxygen sensor data and performing exhaust backpressure tests.

Catalytic converter replacement requires the correct converter for your vehicle's engine, emissions system, and Washington State requirements. We use converters that meet EPA and CARB standards as required. Spokane drivers should know that converter theft has become a significant problem locally, and we can advise on deterrent options. A failing converter that is ignored can cause engine damage from excessive exhaust backpressure. Call (509) 487-0161 for a quote.

What to Expect from Catalytic Converter Replacement

  1. 1

    Confirm converter failure

    We test O2 sensor efficiency ratios, measure exhaust backpressure, and inspect the converter for physical damage or rattling internals.

  2. 2

    Replace converter

    The failed converter is removed and a new EPA or CARB compliant unit is installed with new gaskets, hardware, and O2 sensor ports.

  3. 3

    Verify & drive

    The exhaust system is checked for leaks, O2 sensor data is verified, codes are cleared, and the vehicle is driven to confirm the catalytic efficiency monitor passes.

When You Might Need Catalytic Converter Replacement

  • Check engine light with codes P0420 or P0430 indicating catalyst efficiency below threshold
  • Rotten egg or sulfur smell from the exhaust, especially under acceleration
  • Rattling noise from underneath the vehicle or noticeably reduced engine power
