You know the stuff that causes acid rain and smog. The rear O2 monitors the function of only the front converter.
Now move that converter two feet further down stream and replace it with an "inefficient" emission wise HiFlow converter and your doing very little for the total emissions reduction. So with long tubes and HiFlow cats, you will get a CEL because the threshold window cannot be met.
The emissions system is not reducing the HCs or CO effectively and is by no way altering the NOx being produced. So why spend the extra money if they do not work?
You said previously that cats produced 15 more RWHP than cat-less. Pretend I'm from Missouri and show me, please.

no didn't. I said that high flow cats can provide 15 whp over stock cats. hf cats vs no cats is negligible.
no one here is talking about emissions. we are talking about the effects of a tune with headers/cats. however, you have merely restated what I already stated. the rear o2 sensor does not function properly when moved downstream, whether a cat is moved downstream or removed is moot. we aren't concerned with placement of stock cats.
I am glad you care about the environment and I am impressed by your understanding of the catalyst system. what I am not impressed with is your lack of understanding regarding the conversation.
after reading back, I see where your confusion is sourced. you said what's the point of high flow cats while commenting on factory cats. this means to me that you are arguing for stock and not changing it. what you are really saying is what's the point in cats, just go catless however you made no mention of catless in your comment.
