I plan on having a tune done in a couple of months and will have the rear O2's truned off but I may install a y-pipe before then.

As a matter of fact, I have just got one delivered. It has all 4 bungs, and is not flattened. The only thing is that the loose flange is backwards and can't be flipped on this one. Someone would have to cut and re-weld the pipe...DOH
May fix it, may return it, don't know yet.
