I need to replace my catalytic converters and i've been searching high and low. My local carmax (where I bought it used 2 yrs. ago) wants to charge $5000 (!!!!!!) to replace them and my mass air flow sensor. I can buy the MAF and install it in 5 minutes and save myself hundreds but the catalytic converters are a little more expensive. I've heard they sell for $1000 ea. But that would still save me a whole lot. I just need to know where I can buy them.
Any help is greatfully appreciated.
