Quick facts
- Part: Walker Exhaust 54686 catalytic converter
- Fits: 2005-2006 Nissan Altima V6 3.5L and other vehicles
- Material: Stainless steel
- Condition: New
A worn converter can show up as a rattle, reduced power or an emissions check engine light. With the engine off, start with the stored trouble code and any soot or rust at the tailpipe; a shop can run the tests that need the engine running. Find the cause first, since a misfire or a failing oxygen sensor can set an emissions code too.
