I'm a Honda tech and have an Insight that's been waiting on a catalytic converter for 2 months.
Cons: waiting for two months
Vehicle:

Catalytic converter will sound like a rattling underneath the car towards the rear.
Cons: rattling catalytic converter
Vehicle:
Honda Element
So anywho, I ordered a replacement and bolted everything back together. Cat put me slightly above budget, but hell... half the car is new at this point. Also, I got 34mpg over ~150 miles of test driving to and from work before I decided to investigate the cat; that's pretty good for what amounts to a 16 mile round trip with the AC going.
Pros: good mpg
Cons: slightly above budget
