Default Anyone Using After Cat O2 Dummies?

I heard from a vendor that "A Lot of the 'others' O2 after cat sensors replicators (dummies for removed CATS) are causing codes when installed, I called breathless performance products and they said ever once in a while it will throw a code but that the computer is fine and getting the proper signal. ( I don't like codes on my screen EVER) I have always thought once you got a code, your computer went in to a less then max power mode (limp home) and performance would be less as a result of going in to limp home mode or some such mode.

Anyone installed these sensors yet? If so where did you find the wire plugs to plug in to as I think the dummies plug in under the hood as you should need to be near the hot exhaust... Any diagrams or any help would be greatly appreciated. Thank you, Some very nice cars on this board, glad I was turned on to this BBS.

I've removed my pre cats and cats on my 2001. I also used the Breathless Performance 02 simulators to AVOIDany codes.

Over 8 months now since I pulled the cats. No problems. Simply replace the factory 02 sensors.That's it!
