What's the optimum location for tapping in a wideband O2 sensor to the stock downpipe? At the collector, or further up/downstream?

When your enemy is making a mistake, do not interrupt him.
If it has a cat just downstream of it or just downstream of where the merge is (if u have one ) so it reads good. Make sure it’s in the top section or at least 30deg up from parallel with the road as this will keep the condensation water out of it.
