When you lift/remove the heat shield, you will see the flat spots that represent the stock Euro locations for their O2's. That's why they were mounted there (much like others on this forum). It's clear to see where they 'should' go. Can you please expand on your idea so I understand where you're suggesting? Please use my pic as a reference.
