Okay, I have a 2000 Accord LX 4cyl 5spd ULEV (California type I guess).
I recently started experiencing a rattling under the car during take offs and some during idling at rest...
I figured that this was just my cat. con. heat shield (I had the same problem on my 1990 Accord and just removed the shield.)

Well it isn't. There's some loose parts inside the cat.. Great. Okay, to add to it, I have the ULEV version (I'm in MD) so there is no aftermarket Cat. compatible with my car. I have to get the California compatible one.

Aftermarket Catalytic Convertor (not California Emissions) - $289.45
(California Emissions) Catalytic Convertor - $1489.50

Can somebody point me in the right direction as to where I can find a reasonable price on a Catalytic Convertor for a 2000 Accord LX 4cyl ULEV???
Please?!?!?!?!?

Does that price even sound right?
