O2 sensor crosstalk?

So basically it is your position that only exhaust manufactures know what they are talking about. Let me share a little secret with you; not everyone who knows their **** has an ad in the magazine sitting on the back of your toilet. Unfortunately most of the guys who could provide qualified input at tot busy building stuff in the garage to surf forums and argue aimlessly with halfwits. There is only so much to know about exhaust, it doesn't take a lifelong study by a scientific genius to build a good system. In fact a few hours reading the right material you can have a sound grasp of the fundamentals. And even if your not that smart, you can buy cheap software to help you design a system. As far as products marketed as "dyno tuned", dyno tuned for what, my bike, your bike? I don't think so. You can't tune a pipe on the dyno on one bike and then put it on a different bike and expect it to perform the same. You can build a pipe designed to compliment a specific build profile, but it would only work well on bikes with the exact same build. I just have to laugh at any claim of any dyno tuned bolt on product.
The cross tak would be the same as say VH short shots I think it is, where they just dump by the tranny cover, anyways if you don't have the right baffle or correct back pressure it will pull fresh air in and give a incorrect O2 readings and we all know this. It's the same with the factory pipe on the newer bikes the O2 sensor are located further down the exhaust than the non cat bikes. The right cam, intake, and mufflers and removing the cat can cause the same issue at lower rpms.
If your getting cross talk it would be at the lower RPMs until the gases get moving steadily through the system. I would think that you would see the bike in a tuner trying to correct itself or giving funky air/fuel ratios and running a little ruff at the lower rpms.
And thats my 2c

Absolutly not necessary, no cause for apology, were all just swapping ideas here trying to learn more everyday.

I didn't read this whole pissing match.
But 2 things.
1) I believe some of these crosstalk issues are a result of folks putting the o2 sensors in the wrong positions
2) for the folks that think catalytic converters aren't restrictive. Get on your bicycle and take a ride around the block. NOW... Pop the screen outta your front door and hold it in front of you and take the same ride around the block.
I have a catless head pipe and vieds on my 2011 street glide. It's runs as well if not better than the day I rode it home from the stealer. (it just kicks off a lot less heat)

Oxygen Sensor X-Talk is Moose-Pucky.
I suppose that the Computer program "might" (and even this would be a stretch) have an algorithm that takes each sensors values into account when calculating any adjustment to one Cylinders fuel delivery program . . . but I seriously doubt it.
