Also, cats are not as expensive as they used to be for regular cars.
The one we put on was $36 brand new in the box.

A place like Midas probably buys by the truckload, so they might pay
say $25. If they charge you say $80 installed, they made $55 in about
20 minutes. As long as there were no other complications, you would've
been charged for them as well. The mechanic probably makes between $15
and $25 an hour. This should be billing at 3X that. It might be more in
this type of business because it can be high maintainence. Three X is
just a rule of thumb though, high cielings cost energy in the winter at
least, and mess with the bottom line.

Last cat I had put in a car was $100 at the local muffler shop, but
this was a couple of years ago. It seems there is a new manufacturer or
something out there.
