Whenever doing exhaust gaskets and pipes, you absolutely have to go in stages a little at a time so they seal properly. A lot of times they just tighten each one down hard and it will bend it sideways and will leak. This isn't for sure what's going on but it could be. If it doesn't work I'd swap out the front and rear oxygen sensors with Densos.
