To get the O2 sensors close enough to the engine, they had to be located into a single header tube. The collector is 1/3 the way down the pipes that you can see on the car. Also my pipes are jet hot coated. I don't like the idea of welding bungs into my side pipes. Is there a way to just slide the wide band O2 sensor up the side pipe from the outlet?

Also I have read some comments that some wide band O2 update rate is so slow compared to how fast the rpm comes up that it gives you numbers but you don't actually know what the rpms were, making it hard to correct your tables. Is wide band O2 the best technology to use? Are some O2 much better than others?
