Careful low cost replacements and so called high flow cats are thin in catalyst material so many don't function well beyond a year or two at best!The price of platnium/rhodium/pladimum have skyrocketed so the oems are $600+ without piping.................why not used low mileage oem from a wreck?
I assume you are above 100k limit where EPA requires oem cats?
