Take it all to an exhaust shop and ask them to cut your stuff out and weld the new stuff in.
If you want to replace the resonator in the middle of the two Y pipe sections instead of just using a straight pipe you can. I believe the factory resonator is a glasspack type? You can put in whatever. Search exhaust on this subforum and my username and you will find a post or two about how each different resonator/muffler type sound
Just search for an exhaust shop on google or yelp and find one with good reviews. Go there and ask them to take a look and see what they would charge to weld in new stuff where you need replacing. You can even re-use the flanges so you can still unbolt exhaust pieces but the extra bit of welding will probably raise the price like $5 per piece.

To close this story - RockAuto admitted that they had the wrong part for me, so I was able to return almost everything for free with full refund.
My mechanic was able to find a reasonable deal for the correct part and installed it for me.
All good now!
