Are high flow cats legal?
 
i am in NJ and was wondering if HFCs are street legal. i know they free up a lot of power but i wouldnt want to deal with the hassle of getting it inspected

I think it depends on the exhaust AND the state. If you read some of the manufacturer's descriptions, they'll say "49 state compliant" or whatever, which I"m assuming only excludes California.

usually, they are legal, however....
It is against federal law to replace your cats unless the original ones are damaged.

iirc they are illegal in ny/nj

HFC's look just like stock Cats minus the heat shield, you will pass any visual inspection, so regardless of legality, as long as the car meets emissions, which it will, you'll be just fine. Now go get some :)

I guess it'd be wirthwhile to drill a hole through the original cats...lol

That or pour some old engine oil in the engine side....

speaking of the original cats, have any of you actually cut one open? Jesuchristo, no wonder the HFC's unlock so much power.

I highly recommend NOT cutting one open! asbestos is present.

As Mike stated, replacing the stock cats are illeagal if they are not damaged - there is also a 10K federal fine that goes along with replacing the stocking cats if they're are not damaged. The good thing is no one cares so you are fine.

i always wondered how they could judge if the cats were damaged. would they make you prove that the cats were broke by keeping the old ones for proof?

How can they force you to keep something broken?
Only way I can see it being a problem is if you are caught in the act of changing the cats on your personal property.
