sooo.... i thought i only had one CAT broken sounding like cans.... but NOW i just got a CEL up and scanned it and it said BOTH are broken! so now i need replacement CAT's.

anyone know where i can buy some cheap CA state legal ones or point me in the right direction? i only have about 400 dollars to spend on parts and labor. shops are giving me retarded prices like 750 dollars for both w/ labor...
