I have a set of brand new catly converters for an 02 ls1 fbody. Yes these are new OEM GM cats that have NEVER BEEN INSTALLED OR RAN. With new gaskets. Asking $700 obo , i paid over $1000 at a local dealer for these for a highmileage car, never used them and am tired of looking at them. I have paypal and great feedback!

 

just asking but what would be the advantage of the oem cats over high flow cats from like magnaflow which are priced much lowered?

 

some states require obdII cars to use oem cats in oem locations for emissions tests
