Catalytic Converter Theft : Targeting Prius 

They are after the platinum group metals in the OEM converter, scrap value that increased sharply in recent history. 

Here $200 of replacement parts from Amazon + $60 of tools are used to replace the downstream O2 sensor & two stage 3 way catalytic converter. I also performed an early engine oil & filter change since I had it up on jack stands already. 

Ended up taking it to Pro Exhaust in Auburn, Wa, USA so they could mount & weld the new converter set & o2 sensor. I used my ScanGauge II plugged into the OBDII port to reset the P0420 codes from the ECU, triggered by the loss of the OEM O2 sensor. 

Now the 2005 Toyota Prius much less loud & actually getting better fuel economy now with the new exhaust system / a mysterious phenomenon that I must investigate more // 

So glad the Prius not deafeningly loud now. It still has a straight pipe (muffler delete) but nothing too loud // Glad the master warning light finally off too! 

I gave it a solid DIY effort but the pro' exhaust guys had a nice mig welder & lift which proved essential to this repair & a nominal charge // worth it 

I hope no one steals this one // God willing! 

Godspeed & safe travels friends! Thanks for watching!
