2007 catalytic converter - where to buy

At work last night in the Lowes parking lot someone cut off my cat converter. They got 2 other Toyota trucks also. All easy picking with lots of room under there. Where can I buy one of these at a decent price? CSToyota shows list price as $1,545.00 and their price is $1,158.00. I've been unable to find aftermarket converters so far.

Also, can you run a straight pipe on the 2.7 Liter motor instead of the cat? I know there's an O2 sensor that needs to be installed there but you used to be able to do this years back.

Been laid off a while now and only working weekends at Lowes so money for a new converter is pretty tight right now. I'll no longer be parking at the back fence far from the building. Instead I'm going to park right up front as close to the door as I can get. Better a bunch of door dings than this.

Thanks for any leads.

 

Thanks very much for that lead. My insurance has a $1,000 deductible on both comprehensive and collision so my upfront cost would be high and I don't think I'd get much back.
