Which port for WB O2?
 

I'm thinking it goes in the second port in the DP. First port is stock O2, second one is WB. Third port in midpipe after the cat is second stock O2, correct? Installing AEM UEGO tonight and just wanted confirmation.

I think the port closest to the front is too close for a turbo setup, I welded in another bung between the two, in front of the cat (well my cat is sitting on my bench, but you know what I mean.)

sounds correct.

You can put the second bung before or after the flex joint. Either way, it works fine.
