Until the damn thing was cut off, I never really gave it any thought.
Yes, OEM cats are definitely much better. They have more precious metals than found in cheap aftermarket replacements.

I believe the OE manufacture is Futaba for most cats that are on Toyota vehicles.

The cheaper aftermarket cats will cause your CEL light to come on, and it will set a code for Catalyst Efficiency Below Threshold. These ECU's are very sensitive, I believe the threshold is somewhere north of 95% efficiency.

Some installers indicated possible false alarm issues with sensitivity set so low.

I was thinking skid plates mounted with security bolts (special heads) that covered the converters might send a would be thief to a different target. From my readings on stolen converters it would seem Lexus RX models are a common targets and was hoping someone on here was able to find a way to harden the target.
The sensor ought to pick it up. They're pretty sensitive to car body vibrations. If I as much as kick the tire on my IS, it will trigger the first stage of alarm. I don't think it would be possible to remove a piece of exhaust without triggering it. And one can be added to the oem system. Probably would cost less than $100.

Go with the Viper system. No way someone can take a sawzall to your vehicle without the alarm going off even with the most basic module. You can add in any other modules you need:

remote start
windows up/down
motion sensor
etc

BTW, I've used aftermarket cat converters (Magnaflow) previously and never had a CEL. Just have to find an OEM equivalent.

Tom34,

It is just remarkable that such a market for stolen parts exists. I am either just really naive or perhaps we are insulated from much of that living out here in Idaho. The worst thing I have had to deal with was a stolen license plate.

With nothing positive re: alarm availability for that area of the car, and a bracket underneath would have to be such that it wouldn't cause extra heat to build up that could become an issue, reduce the crime of opportunity. The best defense when you can't have it in your garage is be extremely careful where you park. Never in dark areas where there is not a lot of foot traffic. The converters are sold for the precious metal recovery, not to be re-used on another car.

cats aren't for resale but instead recycle shop will purpose these goods for good chunk of change. 5-10min work for $50-$100 is a sweat deal for these low life. just like theft of copper gutters that are on the house/building and cutting copper wires from live light poles etc. crazy as it may sound but apparently its a lucrative operation.

Hey Doug,

Property crime is out of control in the Mid Atlantic States and sadly enough one gets used to a certain amount of it but sawing off Catalytic Converters in broad daylight in a heavily traveled hospital parking lot seems a bit much.
