So I've read through a lot of the threads and think I have enough information to not f!*K up ordering what I need. Just like some feedback to see if I missed anything or am ordering junk.

Hedman 68478 Shorty Coated headers
Hedman Oxygen Reducers 3in to 3in
Walker Super flow cats (plan on taking out the A.I.R. System)
Cherry Bomb 12" mufflers
New Bosch O2 sensors

Gonna take it to a local shop and have them run weld it all up. Plan on having duals and having both pipes exit in front of the right rear wheel. Still debating if I should get an X-pipe.
