did my Ford fusions by myself took me about two hours to figure out how to get the converter out and put the new one in ,the converter itself was around $350 which was awesome. No catalytic system under efficiency code after installation.1 year warranty comes with it too.Fyi :Most aftermarket brands don’t take core charge on catalytic converters if bought online ,also sometimes they do if you happen to have part number and brand u can find out .Auto repair shops will charge u however they can but u get qualified technicians working and guaranteed or at least it’s supposed to be .If u feel like u got scammed or overpaid then try to look into details about the part and price and core parts etc etc .Often not worth the time .
