How Much Does a Catalytic Converter Cost?
A catalytic converter is an expensive part — but it’s often not the root cause. A Cranbourne West specialist explains.
What drives the cost
Cat cost is driven by the part (they contain precious metals and are costly, more so for European cars). Crucially, a cat usually fails because of another fault (a misfire, oil burning or rich running) — so fixing only the cat without the cause means the new one fails too.
Accurate diagnosis can also reveal it’s a sensor (cheap), not the cat itself.
What the job involves
We confirm the cat is genuinely faulty (not a sensor), fix the underlying cause, then replace the converter with a quality part if needed.
You get an honest diagnosis and a fixed written quote — never an automatic cat sale.
