around 125-300 at a muffler shop depends on brand etc, (plus labor) if they are pre convertors or the main one. A muffler shop can do it cheapest and is fairly routine for them
Two catalytic converters, a left side and a right side.
According to Meineke, they are asking $1,300 to replace the two converters.
a perfect condition second hand megatone drum kit from cash converters like my black one, would cost about $450
Yes
You can find a lot of converters at www.download.com but most are on a trial base and cost
That depends where you buy the converters and who puts them on. You may also need to be prepared to replace the fore and aft sensors, one before each converter and one after each. Two years ago on my '96 it would have cost me $1400+, but I found the converters online for $169 each and the shop installed them for me for a total of $385. This was a pretty good deal. Don't remember how much the sensors cost, but I had to replace four of those, dual exhaust.
Depends on what size it is
That converter costs about $100
Violation of Federal law to do so
Could be your catalystic converter messing up.
Depends on model and year and condition of exhaust. Replacement converters are as little as $250, installation not included. Add another $250 to $500 for installation.
