I need a new Catalyic Convertor for a ULEV 2000 Accord LX 4cyl.

I was getting a rattling under the car during takeoffs and some during idling. I figured it was the heat shield on my cat. con. (I had the same problem with my 1990 Accord LX). So, I take it to get looked at by my mechanic.

He discovers that there is something rattling INSIDE the cat. con which apparently means I need to replace the whole thing. Fine. What's the cost?

They check it out for me...

Aftermarket Catalytic Convertor (NOT compatible with ULEV) - $289.45
(ULEV Compatible) Catalytic Covertor - $1489.50

Okay, so can anybody help me find a cat. con on the net for a ULEV ACCORD???

PLEASE!!!! I can BARELY afford that $289.45!!! But $1500???? Is that real?
