Hey guys just wondering as there is a lot of talk about this but with out emissions standards, does anybody here have a high flow cat on their exhaust setup and took it in for etest?

I've heard it will fail and I do somewhat understand why but some people are trying to tell me otherwise.

people have passed. But having one doesn't help you.

i passed with one. But then again they tested my car as a hot rod.

Passed with flying colours. 2speed idle test.

well I'm doing mine as a hot rod because of the swap.

2.5" collector, whatever cat, 2.25" piping back to muffler.

high flow cats tend to only pass when they are relatively new. if ur riding on them for 50k then likely you wont pass because many of them recommend that they be changed at specific intervals

What engine into what car?

getting your car tested as a hot rod puts it in a different class. it's said that the limits are less sritct(spl) then if it was the same engine that's in your VIN

when ur car is tested as a hot rod it goes by the standards in 1984 or 1986 (i think its 20 years ago, but not 100% on that).
But in order to be classified as a hot rod your engine needs to be of larger displacement than any engine offered it that model year car. So going from a d15/d16 to a b16 isn't going to get you classified as a hot rod....unless the place you take the car doesn't know what a b18 looks like....wink wink.
When i took my car for the last etest it was tested as a hot rod and the limits were almost 5 times higher than compared to stock.

when you go get the test make sure the car is nice and hot, cats have a high operating temp.

there are a bunch of tricks out there to increase your odds of passing. I think running on an empty tank also helps, just look it up on google.

well they will definately run your car as a hot rod, so i wouldn't worry at all about having a high flow cat. Like i said before the limits are way higher when run as a hot rod. But i would still go for a 25 minute cruise (preferrably highway speeds) before going for the test.

ok man, might end up buying the high flow cat if I can't find a jdm itr one.

thanks man
