[kirby26]

i have a 00 maxima, recently i had purchased a an HKS exhaust. i have to replace the cat so i am going to get a high flow, jus dont know wich one to buy. was looking at a "Bomz Raceing." trying to stay around 100-150 buks

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?

Also, check with your dealer. I know the dealer here stands behind their 8 year warranty on emissions parts, original owner or not, unlimited miles. If it's out, make them replace it.

i will check with the dealer. so you are basically sugesting i replace it with a factory cat, and yes i am above 100k

You dont need a high flow cat the factory cat flows just as well as any aftermarket cat. You shouldn't need to replace it because of your new exhaust it should work just fine.
