no, the flanges, y-pipe, converter style..the whole shebang really....is different.
if youve got a damaged or plugged cat, your best bet is an aftermarket universal (you'll have to have a muffler shop weld in on for you, shouldnt be more than $20 or so).
if your current cats are OK, then leave them be. there are no performance gains to be had by replacing a properly functioning cat.
